DESCRIPTION:Title: Dirichlet-type spaces on the unit ball and joint 2-isometries\nby
Sameer Chavan (IIT Kanpur) as part of Webinars on Operator Theory and Ope
rator Algebras\n\n\nAbstract\nWe discuss a formula that relates the spheri
cal moments of the multiplication tuple on a Dirichlet-type space to a com
plex moment problem in several variables. This can be seen as the ball-ana
logue of a formula originally invented by Richter. One may capitalize on t
his formula to study Dirichlet-type spaces on the unit ball and joint 2-is
ometries. This talk is based on a joint work with Rajeev Gupta and Md Rami

DESCRIPTION:Title: Quantum group contraction and bosonisation\nby Sutanu Roy (NISER)
as part of Webinars on Operator Theory and Operator Algebras\n\n\nAbstrac
t\nAbstract: In 1953 İnönü and Wigner introduced group contraction: a
systematic (limiting) process to obtain from a given Lie group a non-isomo
rphic Lie group. For example\, the contraction of SU(2) group (with respec
t to its closed subgroup T) is isomorphic to the double cover of E(2) grou
p. The q-deformed C*-algebraic analogue of this example was introduced and
investigated by Woronowicz during the mid '80s to early '90s. More precis
ely\, the C*-algebraic deformations of SU(2) and (the double cover of) E(2
) with respect to real deformation parameters 0<|q|<1 become compact (deno
ted by SUq(2)) and non-compact locally compact (denoted by Eq(2)) quantum
groups\, respectively. Furthermore\, the contraction of SUq(2) groups beco
mes (isomorphic) to Eq(2) groups. However\, for complex deformation parame
ters 0<|q|<1\, the objects SUq(2) and Eq(2) are not ordinary but braided q
uantum groups. More generally\, the quantum analogue of the normal subgrou
p of a semidirect product group becomes a braided quantum group and the r
econstruction process of the semidirect product quantum group from a braid
ed quantum group is called bosonisation. In this talk\, we shall present a
braided version of the contraction procedure between SUq(2) and Eq(2) gro
ups (for complex deformation parameters 0<|q|<1) and address its compatibi
lity with bosonisation. This is based on a joint work with Atibur Rahaman.

ry states that if $(M\, g)$ is a Riemannian manifold\, then there exists a
unique connection on $M$ which is torsionless and compatible with $g$. Th
e curvature of the manifold is then computed from this particular connecti
on. \n\nWe will try to explain the notions to state and prove Levi-Civita'

DESCRIPTION:Title: On the geometry of the symmetrized bidisc\nby Tirthankar Bhattach
aryya (IISc Bangalore) as part of Webinars on Operator Theory and Operator
Algebras\n\n\nAbstract\nWe study the action of the automorphism group of
the $2$ complex dimensional manifold symmetrized bidisc $\\mathbb G$ on it
self. The automorphism group is $3$ real dimensional. It foliates $\\mathb
b G$ into leaves all of which are $3$ real dimensional hypersurfaces excep
t one\, viz.\, the royal variety. This leads us to investigate Isaev's cla
ssification of all Kobayashi-hyperbolic $2$ complex dimensional manifolds
for which the group of holomorphic automorphisms has real dimension $3$ s
tudied by Isaev. Indeed\, we produce a biholomorphism between the symmetri
zed bidisc and the domain\n\n \\[\\{(z_1\,z_2)\\in \\mathbb{C} ^2 : 1+|z_1
|^2-|z_2|^2>|1+ z_1 ^2 -z_2 ^2|\, Im(z_1 (1+\\overline{z_2}))>0\\}\\]\n\ni
n Isaev's list. Isaev calls it $\\mathcal D_1$. The road to the biholomorp
hism is paved with various geometric insights about $\\mathbb G$. \n\nSeve
ral consequences of the biholomorphism follow including two new characteri
zations of the symmetrized bidisc and several new characterizations of $\\
mathcal D_1$. Among the results on $\\mathcal D_1$\, of particular interes
t is the fact that $\\mathcal D_1$ is a ``symmetrization''. When we symmet
rize (appropriately defined in the context) either $\\Omega_1$ or $\\mathc
al{D}^{(2)} _1$ (Isaev's notation)\, we get $\\mathcal D_1$. These two do
mains $\\Omega_1$ and $\\mathcal{D}^{(2)} _1$ are in Isaev's list and he m
entioned that these are biholomorphic to $\\mathbb D \\times \\mathbb D$.
We produce explicit biholomorphisms between these domains and $\\D \\times
\\D$.\n

DESCRIPTION:Title: Bisynchronous Games\nby Mizanur Rahaman (BITS Pilani Goa campus)
as part of Webinars on Operator Theory and Operator Algebras\n\n\nAbstract
\nFor some games played by two cooperating but non-communicating players\,
the players can use entanglement as a resource to improve their outcomes
beyond what is possible classically. Graph colouring game\, graph homomorp
hism game and graph isomorphism game are a few examples of these games. Ov
er the last few years\, a remarkable progress has been taken place in the
theory of these non-local games. One significant aspect of this developmen
t is its connection with many challenging problems in operator algebras.\n
\nIn this talk\, I will review the theory of these games and explain the r
elevant connection with operator algebras. In particular\, I will introduc
e a new class of games which is called bisynchronous and will show a close
connection between bisynchronous games and the theory of quantum groups.
Moreover\, when the number of inputs is equal to the number of outputs\, e
ach bisynchronous correlation gives rise to a completely positive map whic
h will be shown to be factorable in the sense of Haagerup and Musat. This
is a joint work with Vern Paulsen. No background in quantum theory is need

DESCRIPTION:Title: What is a Murray-von Neumann algebra?\nby Soumyashant Nayak (ISI
Bangalore) as part of Webinars on Operator Theory and Operator Algebras\n\
n\nAbstract\nIt was observed by Murray and von Neumann in their seminal pa
per on rings of operators (1936) that the set of closed\, densely-defined
operators affiliated with a finite von Neumann algebra has the structure o
f a *-algebra. The algebra of affiliated operators naturally appears in ma
ny contexts\; for instance\, in the setting of group von Neumann algebras
in the study of non-compact spaces and infinite group actions. In this tal
k\, we will give an intrinsic description of Murray-von Neumann algebras a
voiding reference to a Hilbert space\, thus\, revealing the intrinsic natu
re of various notions associated with such affiliated operators. In fact\,
we will view Murray-von Neumann algebras as ordered complex topological *
-algebras arising from a functorial construction over finite von Neumann a
lgebras.\n

DESCRIPTION:Title: An asymmetric multiparameter CCR flow\nby S Sundar (IMSc Chennai)
as part of Webinars on Operator Theory and Operator Algebras\n\n\nAbstrac
t\nThe theory of E_0-semigroups initiated by R.T. Powers and developed ext
ensively by Arveson has been an active area of research for well over thir
ty years. An E_0-semigroup is a 1-parameter semigroup of unital normal *-e
ndomorphisms of B(H) where H is a Hilbert space.\n\nHowever\, nothing prev
ents us from considering semigroups of endomorphisms indexed by more gene
ral semigroups. This was analysed in collaboration with Anbu Arjunan\, S.
P. Murugan and R. Srinivasan. \n\nI will explain a few similarities betwe
en the one parameter theory and the multiparameter theory. Also\, there a
re significant differences. I will attempt to illustrate one difference by
explaining that a multiparameter CCR flow need not be symmetric.\n

ukherjee (University of Goettingen) as part of Webinars on Operator Theory
and Operator Algebras\n\n\nAbstract\nIn this talk\, we describe a framewo
rk to study non-commutative geometry as a relative version of differential
geometry. More precisely\, given a C*-algebra A\, we would like to make s
ense of a "smooth" subalgebra $A^\\infty \\subseteq A$\, and deduce proper
ties about A using such a subalgebra. Such a smooth subalgebra should be
analogous to the Frechet algebra $C^\\infty(M) \\subseteq C(M)$ for a smoo
th manifold M\, in the world of commutative C*-algebras. We shall review
the fundamental properties and applications of such embeddings\, called $\
\textit{isoradial embeddings}$\, due to Ralf Meyer. If time permits\, I wi
ll mention an ongoing research program with Meyer\, Corti\\~nas and Cuntz\
, that uses such embeddings to develop noncommutative geometry over finite
fields. \n\nI will not assume that the audience has any background beyon
d familiar examples of C*-algebras. A lot of the motivation would however
be clearer to those familiar with cyclic homology or operator algebraic K-
theory.\n

olel (Technion - Israel Institute of Technology) as part of Webinars on Op

neralize results of Sarkar and of Bhattacharjee-Eschmeier-Keshari-Sarkar
concerning invariant subspaces for commuting tuples of operators. These au
thors prove Beurling-Lax-Halmos type results for commuting tuples $T=(T_1\
,\\ldots\,T_d)$ operators that are contractive and pure\; that is $\\Phi_T
(I)\\leq I$ and $\\Phi_T^n(I)\\searrow 0$ where $$\\Phi_T(a)=\\Sigma_i T_i
aT_i^*.$$\n\nHere we generalize some of their results to commuting tuples
$T$ satisfying similar conditions but for $$\\Phi_T(a)=\\Sigma_{\\alpha \
\in \\mathbb{F}^+_d} x_{|\\alpha|}T_{\\alpha}aT_{\\alpha}^*$$ where $\\{x_
k\\}$ is a sequence of non negative numbers satisfying some natural condit
ions (where $T_{\\alpha}=T_{\\alpha(1)}\\cdots T_{\\alpha(k)}$ for $k=|\\a
lpha|$). In fact\, we deal with a more general situation where each $x_k$
is replaced by a $d^k\\times d^k$ matrix.\n\nWe also apply these results t
o subspaces of certain reproducing kernel correspondences $E_K$ (associate
d with maps-valued kernels $K$) that are invariant under the multipliers g
iven by the coordinate functions.\n

/a>\nby Ved Prakash Gupta (JNU) as part of Webinars on Operator Theory and
Operator Algebras\n\n\nAbstract\nThe study of the lattice of intermediate
objects of a pair $B \\subset A$ in any category is quite a natural and f
undamental question and has a significant say in obtaining a better unders
tanding of the structures of the objects A and B. A good deal of work in t
his direction has been done in the category of finite groups\, both of qua
litative and quantitave flavour. Its natural analogue in the theory of ope
rator algebras has had some success\, though mainly quantitative in nature
and based on some existing tools. Continuing the trend\, in a recent work
with Keshab Chandra Bakshi\, we developed certain tools in the category o
f simple C*-algebras (motivated by and analogous to the ones existing in t
he category of simple von Neumann algebras) to answer a quantitative quest
ion of Roberto Longo regarding the lattice of intermediate von Neumann sub
algebras of an inclusion of type III factors. We shall present some essenc

$-algebra $A$ via a map $\\alpha$\, the triple $(A\, G\, \\alpha)$ is said
to be a $C^*$-dynamical system\, then we can associate a $C^*$-algebra ca

application of famous Hall's Marriage Theorem\, we can obtain a set of co
set representatives which acts simultaneously as representatives of both
left and right cosets of H in G. Given a subfactor $N\\subset M$ with fini
te Jones index\, M can be regarded as a left as well as a right N-module.
Pimsner and Popa proved that M is finitely generated as a left (equivalent
ly\, right) N-module. About a decade back\, Vaughan Jones asked whether on
e can find a common set which acts simultaneously as a left and a right ge
nerating set. As a naive attempt in this direction\, we answer this questi
on in the affirmative for a large class of integer index subfactors. We al
