DESCRIPTION:Title: Formalisms of gluing Fukaya categories\nby Hiro Lee Tanaka
(Texas State University) as part of Western Hemisphere virtual symplectic
seminar\n\n\nAbstract\nIn the Weinstein setting\, we know that wrapped Fu
kaya categories glue\, so it behooves us to understand a general framework
that captures the properties of this gluing. After explaining a few appro
aches of how to formalize gluing procedures in the 2-dimensional setting\,
we'll explain why we think a framework inspired by factorization homology
seems most promising to capture the general behavior of local-to-global i
nvariants of Weinstein sectors. Setting up this formalism sheds insights i
nto things like the following: (a) We can classify all local-to-global inv
ariants of 2-dimensional Liouville sectors. (b) We see that the Floer theo
ry of Lagrangian cobordisms in R^oo recovers the higher K theory of the in
tegers. (We have been unable to compute this higher K theory for decades\,
and a computation would yield powerful results in arithmetic.) (c) Wrappe
d Floer theory can shed insight into higher homotopy groups of Liouville e
mbedding spaces.\n

DESCRIPTION:Title: Homological mirror symmetry for elliptic Hopf surfaces\nby
Abigail Ward (Harvard) as part of Western Hemisphere virtual symplectic s
eminar\n\n\nAbstract\nOne can produce non-Kähler complex surfaces by perf
orming logarithmic transformations on projective elliptic surfaces\; for e
xample\, elliptic Hopf surfaces (including the classical Hopf surface $S^1
\\times S^3$) can be obtained by performing such operations to the produc
t of the projective plane with an elliptic curve. In situations where the
original surface has a mirror symplectic space\, one can ask if there is a
"mirror operation" to the logarithmic transformation\, i.e. a way of prod
ucing a mirror to the logarithmically transformed surface from the origina
l mirror space. We will discuss an answer to this question in the case of
elliptic Hopf surfaces. For each such surface $S$\, we will produce a mirr
or "non-algebraic Landau-Ginzburg model" with an associated Fukaya categor
y. We will relate objects of this Fukaya category to coherent analytic she
aves on $S$.\n

which have vanishing symplectic cohomology but non-vanishing symplectic K-

\, built as a variant of Cohen-Jones-Segal’s Floer homotopy type. The pr

dictionary between counts of pseudoholomorphic cylinders and Z_2-graded
embedded contact homology (ECH) of prequantization bundles over Riemann su
rfaces. We upgrade to a full Z-grading\, and in combination with the doma
in dependent methods introduced by Farris in his thesis\, make use of the
direct limits for filtered ECH established in Hutchings-Taubes proof of th
e Arnold-Chord conjecture to extend the Morse-Bott methods for prequantiza
tion bundles to the realm of ECH. In particular\, we establish that the E
CH of a prequantization bundle over a Riemann surface is isomorphic to the
exterior algebra of the homology of this base. We comment on future wor
k\, which relates the U map in ECH to Gromov-Witten invariants of the base
\, permitting computations of the associated ECH capacities and an expecte
d stabilization result purely in the context of ECH.\n

e-Rham spectral sequence associated to a compact Kahler manifold degenerat
es. Kaledin showed that the non-commutative Hodge-de-Rham spectral sequenc
e associated to a smooth proper dg-category over a field of characteristic
zero degenerates as well. When the category is just smooth or just proper
\, Kontsevich conjectured that certain weaker statements\, which are true
for smooth or proper varieties\, should continue to hold in the categorica
l setting. Recently\, counterexamples to Kontsevich's conjectures were fou
nd by Efimov. I will discuss the background to this story\, and then I wil
l explain why the conjectures of Kontsevich do hold\, for analytic reasons
\, when the category is a Fukaya category. The argument suggests interesti

DESCRIPTION:Title: An annular filtration on Sarkar-Seed-Szabó's spectral sequenc
e\nby Melissa Zhang (University of Georgia) as part of Western Hemisph
ere virtual symplectic seminar\n\n\nAbstract\nKhovanov homology is a combi
natorial invariant of links in the three-sphere borne from structures in r
epresentation theory. Nevertheless\, there are many spectral sequences rel
ating Khovanov homology to geometrically-defined invariants\, such as Ozsv
áth-Szabó's Heegaard Floer homology. Seidel-Smith defined its geometric
counterpart\, symplectic Khovanov homology\, which Abouzaid-Smith showed i
s indeed isomorphic to combinatorial Khovanov homology over characteristic
0. Inspired by symplectic Khovanov homology's O(2) action\, Sarkar-Seed-S
zabó extended Szabó's geometric spectral sequence\, which is a combinato
rial spectral sequence conjectured to be isomorphic to Ozsváth-Szabó's s
pectral sequence (from the Khovanov homology of a knot to the Heegaard Flo
er homology of the branched double cover of its mirror knot). A bifiltered
version of this complex admits a family of Rasmussen-type link invariants
.\n\nIn joint work with Linh Truong\, we show that for links in a solid to
rus (i.e. annular links)\, Sarkar-Seed-Szabó's complex admits third filtr
ation. This annular filtration allows us to define a 2-parameter family of
annular concordance invariants s_{r\,t} analogous to Grigsby-Licata-Wehrl
i's annular Rasmussen invariants d_t (from annular Khovanov-Lee theory). T
he two families share many properties\, including applications to 3D conta
ct geometry and smooth knot concordance.\n

DESCRIPTION:Title: Lifting cobordisms and Kontsevich-type recursions for counts o
f real curves\nby Xujia Chen (Stony Brook University) as part of Weste
rn Hemisphere virtual symplectic seminar\n\n\nAbstract\nKontsevich's recur
sion\, proved by Ruan-Tian in the early 90s\, is a recursion formula for g
enus 0 Gromov-Witten invariants. For symplectic fourfolds and sixfolds wit
h a real structure (i.e. an anti-symplectic involution\, analogue of the u
sual conjugation map on C^n)\, signed invariant counts of real rational ps
eudo-holomorphic curves were defined by Welschinger in 2003. In 2006-07\,
Solomon re-interpreted Welschinger's invariants\, proposed Kontsevich-type
recursion formulas for them\, and suggested a potential adaptation of the
proof in the complex case for confirming them. For many symplectic fourfo
lds and sixfolds\, these recursions determine all invariants from basic in
puts. We establish Solomon's recursions by a different approach: lifting c
obordisms from the moduli spaces of real domains to the moduli space of re
al maps and incorporating the wall-crossing corrections from the walls obs
tructing relative-orientability.\n

very few closed exact Lagrangians (conjecturally only one)\, we will expl
ain that it has many singular Lagrangians in the form of Weinstein subdoma
ins. We first produce flexible subdomains of $T^*S^n$\, which in high-dime
nsions yield exotic Weinstein presentations for $T^*S^n$ as the standard b
all with a single handle attached along an exotic Legendrian knot. The alg
ebraic side of the story for the wrapped Fukaya category is closely connec
ted to a result of Thomason in algebraic K-theory. Then we discuss joint w
ork with Z. Sylvan that associates to every finite collection of prime int
egers a (non-flexible) Weinstein subdomain of $T^*S^n$ whose Fukaya catego
ry is localized at those primes and show that the Fukaya category of any W

me connections between the nearby Lagrangian conjecture and the algebraic

he recent existence result for (twisted) generating functions due to Abouz
aid\, Courte\, Guillermou and Kragh. In work in progress joint with Abouza
id\, Courte and Kragh we find that a certain geometric description of the
splitting map for the algebraic K-theory of a point due to Waldhausen and
Bökstedt gives a new restriction on the framed bordism class of nearby La
grangians. In particular I will show that if L is any Lagrangian homotopy
sphere in the cotangent bundle of the standard sphere\, then the connected
sum of L with itself bounds a parallelizable manifold. This extends known
constraints for the possible class of L in the group of homotopy spheres
modulo those which bound a parallelizable manifold. I will also touch on j
oint work with Igusa concerning the higher torsion of Legendrians in 1-jet
spaces and make some speculations about the higher torsion of nearby Lagr

DESCRIPTION:Title: Obstructing infinite staircases\nby Dan Cristofaro-Gardin

stract\nA landmark result\, due to McDuff and Schlenk\, asserts that in de
termining when a four-dimensional symplectic ellipsoid can be symplectical
ly embedded into a four-dimensional ball\, the answer is given by an “in
finite staircase” determined by the odd-index Fibonacci numbers and the
Golden Mean. There has recently been considerable interest in better under
standing this phenomenon for more general embedding problems. I will expl
ain a theorem showing that for any four-dimensional convex toric domain of
finite type\, if an infinite staircase occurs\, then its singular points
must accumulate at a unique point\, characterized by an explicit quadratic
equation. I will then explain how to apply this theorem to prove that wh
en the target is a rational ellipsoid\, there is an infinite staircase in
precisely three cases -- when the target has "eccentricity" 1\, 2\, or 3/2
\; interestingly\, in each of these cases\, the corresponding embeddings c

DESCRIPTION:Title: SO(3)-instantons and the Atiyah-Floer Conjecture\nby Alia
kbar Daemi (WUSTL) as part of Western Hemisphere virtual symplectic semina
r\n\n\nAbstract\nA useful tool to study a 3-manifold is the space of repre
sentations of its fundamental group into a Lie group. Any 3-manifold can b
e decomposed as the union of two handlebodies. Thus representations of the
3-manifold group into a Lie group can be obtained by intersecting represe
ntation varieties of the two handlebodies. Casson utilized this observatio
n to define his celebrated invariant. Later Taubes introduced an alternati
ve approach to define Casson invariant using more geometrical objects. By
building on Taubes' work\, Floer refined Casson invariant into a 3-manifol
d invariant which is known as instanton Floer homology. The Atiyah-Floer c
onjecture states that Casson's original approach can be also used to defin
e a graded vector space and the resulting invariant of 3-manifolds is isom
orphic to instanton Floer homology. In this talk\, I will discuss a variat
ion of the Atiyah-Floer conjecture\, which states that framed Floer homolo
gy (defined by Kronheimer and Mrowka) is isomorphic to symplectic framed F
loer homology (defined by Wehrheim and Woodward). I will explain how the c
losed-open string map is related to framed Floer homology. Finally I comme
nt on how earlier works of Seidel and Smith might provide useful computati
onal tools for framed Floer homology. This talk is based on a joint work w
ith Kenji Fukaya and Maksim Lipyanskyi.\n

DESCRIPTION:Title: Microlocal sheaf categories and the J-homomorphism\nby Xi
n Jin (Boston College) as part of Western Hemisphere virtual symplectic se
minar\n\n\nAbstract\nThe theory of microlocal sheaves\, developed by Kashi
wara--Schapira\, has found many applications in the study of symplectic to
pology. For a smooth Lagrangian L in a cotangent bundle of a smooth manifo
ld and a commutative ring spectrum k\, one can associate a sheaf of microl
ocal categories\, which is locally constant with fiber equivalent to Mod(k
). It admits a classifying map L--->BPic(k). We will show that the classif
ying map factors through the Gauss map L--->U/O and the delooping of the J
-homomorphism U/O--->BPic(S)\, where S is the sphere spectrum. As an appli
cation\, combining with previous results of Guillermou\, we show that if L
is a compact smooth exact Lagrangian\, then the classifying map is homoto
pically trivial\, recovering a result of Abouzaid--Kragh.\n

DESCRIPTION:Title: Symplectic annular Khovanov homology\nby Cheuk Yu Mak (Ca
mbridge) as part of Western Hemisphere virtual symplectic seminar\n\n\nAbs
tract\nAnnular Khovanov homology is an invariant of annular links (links i
n a solid torus) introduced by Asaeda-Przytycki-Sikora as an analogue of K
hovanov homology for links. Auroux-Grigsby-Wehrli showed that the first pi
ece of the annular Khovanov homology can be identified with the Hochschild
homology of the Fukaya-Seidel category of A_n Milnor fibers with coeffici
ents in braid bimodules. In this talk\, we will introduce a symplectic ver
sion of annular Khovanov homology using Hochschild homology of the Fukaya-
Seidel category of more general type A nilpotent slices. Building on the w
ork of Abouzaid-Smith and Beliakova-Putyra-Wehrli\, we show that the sympl
ectic version is isomorphic to the ordinary version. Finally\, we will exp
lain how to derive a spectral sequence from the symplectic annular Khovano
v homology to the symplectic Khovanov homology directly using symplectic g
eometry. This is based on a joint work with Ivan Smith.\n

DESCRIPTION:Title: The singular Weinstein conjecture\nby Eva Miranda (Univer
sitat Politècnica de Catalunya) as part of Western Hemisphere virtual sym
plectic seminar\n\n\nAbstract\nThe purpose of this talk is to present some
recent results concerning Reeb dynamics on a $b^m$-contact manifolds. b-C
ontact manifolds (and more generally b^m´-contact manifolds) are the odd-
dimensional counterpart to $b^m$-symplectic manifolds which have been a ce
nter of attention in Poisson Geometry. The study of $b^m$-Reeb dynamics is
motivated by well-known problems in fluid dynamics (Beltrami fields) and
celestial mechanics\, where those geometric structures naturally appear.
\n\nThe first part of the talk will focus on the singular Weinstein conjec
ture following https://arxiv.org/abs/2005.09568 (joint work with Cédric
Oms). We prove that in dimension 3 there are always infinite periodic orbi
ts on the critical set (if compact). In particular\, we will prove that th
e dynamics on positive energy level-sets in the restricted planar circular
three-body problem are described by the Reeb vector field of a $b^3$-cont
act form that admits an infinite number of periodic orbits at the critical
set. This investigation goes hand-in-hand with the Weinstein conjecture
on non-compact manifolds having compact ends of convex type. In particular
\, we extend Hofer's arguments to open overtwisted contact manifolds that
are $\\R^+$-invariant in the open ends\, obtaining as a corollary the exis
tence of periodic $b^m$-Reeb orbits away from the critical set.\n\nAt the
end of the talk\, we will focus on singular Reeb orbits (joint work with C
édric Oms and Daniel Peralta-Salas). Inspired by Poincaré's orbits going
to infinity in the (restricted) three-body problem\, we investigate the e
xistence of singular Reeb orbits emanating from/going to the critical set
and we prove their existence for generic Melrose b-contact structures. In
the proof\, we use the correspondence between b-Beltrami vector fields and
b-contact structures.\n
