DESCRIPTION:Title: Wall Crossings and Lagrangian Cobordisms\nby Jeff Hicks (Cam
bridge) as part of Rutgers symplectic geometry seminar\n\n\nAbstract\nWe e
xpect that two Lagrangian submanifolds have matching Floer theoretic invar
iants if they are related by a Hamiltonian isotopy. For example\, an appro
priately weighted count of Maslov index 2 disks with boundary on a Lagrang
ian L should remain unchanged under Hamiltonian isotopy. If the Hamiltonia
n isotopy is not very nice -- say that at some point the isotopy passes th
rough a Lagrangian which bounds a non-regular Maslov index 0 disk -- then
weights used to count the disks need to be corrected by a ``wall crossing
transformation'' to obtain invariance. These transformations end up playin
g an important role in mirror symmetry\, where they are the coordinate tra
nsformations used to build a mirror space from an SYZ fibration.\n\nLagran
gian cobordisms give an equivalence relation on Lagrangian submanifolds wh
ich is weaker than Lagrangian isotopy\, but is still expected to preserve
Floer theory. In this talk\, we look at a first example of a non-cylindric
al Lagrangian cobordism providing an equivalence of Lagrangian Floer theor
y\, and relate this to the story of wall-crossing arising from Hamiltonian
isotopy.\n

DESCRIPTION:Title: Exterior algebras and local mirror symmetry\nby Jack Smith (
Cambridge) as part of Rutgers symplectic geometry seminar\n\n\nAbstract\nT
he exterior algebra plays an important role in mirror symmetry\, as the Fl
oer algebra of a Lagrangian torus bounding no holomorphic discs and as the
Ext-algebra of the corresponding smooth point on the mirror. In the pres
ence of holomorphic discs one obtains an A-infinity deformation of this pi
cture\, and I'll explain how to classify such deformations under a monoton
icity hypothesis. This leads to a simple proof that the Floer algebra of
a monotone torus is the endomorphism algebra of the expected matrix factor
ization of its superpotential\, as well as a purely algebraic result gener
alizing the classification of Clifford algebras by quadratic forms\n

e construct p-adic analytic \nactions on the Fukaya category of a non-deg

ng this\, we deduce \nresults on the change of rank of Lagrangian Floer ho
mology groups \n$HF(\\phi^k(L)\,L')$ as $k$ varies\, for a symplectomorph

DESCRIPTION:Title: Lagrangian links quasimorphisms and non-simplicity of Hameomorph
ism group\nby Cheuk Yu Mak (Edinburgh) as part of Rutgers symplectic g
eometry seminar\n\n\nAbstract\nWe will explain the construction of a seque
nce of homogeneous quasimorphisms of the area preserving homeomorphism gro
up of the disc using Lagrangian Floer theory for links. This sequence of q
uasimorphisms has asymptotically vanishing defect\, so it is asymptoticall
y a homomorphism. We will then explain how studying the subleading asympto
tic of these quasimorphisms enable us to show that the Hameomorphism group
is not the smallest normal subgroup of the area preserving homeomorphism
group. This is a joint work with Daniel Cristofaro-Gardiner\, Vincent Humi
lière\, Sobhan Seyfaddini and Ivan Smith.\n
