: Complete factorization in minimal N=4 Chern-Simons-matter theory
u : RCꎁ()

Tv : I will speak about up-coming work with T.Nosaka on the study of the minimal N=4 Chern-Simons matter theory, that is, N=4 $$U(N)_k \times U(N+M)_{-k}$$ Chern-Simons theory coupling to one bifundamental hyper multiplet employing its partition function, which is given by an $$2N+M$$ dimensional integration via localization. Surprisingly, by performing the integration explicitly the partition function completely factorizes into that of pure Chern-Simons theory for two gauge groups and an analogous contribution from the hypermultiplet. Employing the completely factorized partition function we explicitly show the level/rank duality of the system, which is anticipated by the Hanany-Witten effect of type IIB brane configuration. If time permits, I also comment on the connection to the higher-spin theory in the 't Hooft limit.

: Yang-Baxter deformations and generalized supergravity
u : gcY()

Tv : It is well-known that type IIB superstring theory on the AdS_5 x S^5 background is classically integrable. Recently, integrable deformations of this system have been studied very actively by adopting a systematic way called the Yang-Baxter deformation. In this talk, I will give a review on recent progress on this issue. The deformations under the unimodularity condition lead to solutions of type IIB supergravity including the Lunin-Maldacena backgrounds (dual for beta deformations of the N=4 super Yang-Mills theory), the Maldacena-Russo backgrounds (dual for non-commutative gauge theories) and Schroedinger spacetimes (dual for non-relativistic conformal field theories). In general, however, the resulting deformed backgrounds are not solutions of the standard type IIB supergravity, but of the generalized supergravity. Finally I will describe the relation between noncommutative gauge theories and the generalized supergravity.

: Irregular conformal block and spectral curve
u : Chaiho Rim (Sogang Univ.)

TvFWe present recent developments of irregular states and their inner product using the irregular conformal vertex operator formalism. We augment free field formalism by screening operators and provide the (deformed) spectral curve of the inner product at the Nekrasov-Shatashivili limit. Some of important properties of the spectral curve will be discussed.
