Title: Equivariant Localization in Supergravity

Abstract: We describe a powerful new technique for computing various physical observables in supergravity, without solving the supergravity equations. There are many applications including computing central charges and other BPS quantities of SCFTs dual to AdS solutions, computing Bekenstein entropy of supersymmetric black holes and computing the partition function of d=3 SCFTs on curved manifolds.  We summarise the main ideas and illustrate with some applications.

Title: Solitons, Branes and QCD

Abstract: A lot of advances in research in the field of BPS solitons, branes in string theory, and holographic QCD, have been reported
in the past three decades. The intersection of these three activities brought about a possible unified theory of nuclear physics"Nuclear Matrix Model" which Piljin Yi, Nori Iizuka and myself derived holographically from string theory in 2010. 
I am going to review some important aspects behind the theory and also the results of the model, including reproduction of the magic numbers and nuclear binding energy.

Title: Strong/weak Calabi-Yau/Calabi-Yau correspondence and D-brane transports

Abstract: I will talk about transport of D-branes along paths between phases of 2d linear sigma models with non-Abelian gauge groups. The focus will be on models with two phases, one weakly coupled and the other strongly coupled, both corresponding to Calabi-Yau threefolds. Seiberg-like duality enters in an interesting way.

Title: Toward fundamental building blocks of supersymmetric dualities

Abstract: Since Seiberg's seminal work in 1994, a vast number of examples of supersymmetric infrared dualities have been uncovered. The exploration of these examples has recently revealed numerous unexpected underlying connections among seemingly disparate dualities, motivating the pursuit of fundamental building blocks that could unify such dualities. In line with this pursuit, this talk discusses the deconfinement duality for tensor representation matters in three dimensions, which provides a framework for understanding Seiberg-like dualities involving tensor matters as consequences of those without tensor matters.

Title: On 2d Conformal Field Theories 

Abstract: In this talk, I would review certain aspects of 2d rational conformal field theories  done in last five years by our group.

The topics covered are modular linear differential equations and Hecke transformation for fermionic systems, generalized 

 Monster Moonshine, Deligne series of exceptional Lie algebra, and RCFT related to the intermediate algebras.

Title: On holography and anomalies of D-type 6D (2,0) theories

Abstract: : This talk is an answer to the question: Can the anomaly formula for D-type (2,0) 6D theories - which Piljin derived in 2001 -  be re-derived holographically?

Title: BPS Dendroscopy on Local del Pezzo Surfaces

Abstract: The BPS spectrum in type IIA strings compactified on a Calabi-Yau threefold $X$ depends sensitively on K"ahler moduli, with a dense set of walls separating chambers where the BPS index is constant. The Attractor Flow Tree Formula gives a way to decompose the spectrum into bound states of elementary constituents which no longer depend on Kahler moduli.  When $X$ is the resolution of a toric CY singularity, the BPS spectrum of the corresponding 5D gauge theory can be described near the singularity by a quiver, but this description breaks down at finite volume. Scattering diagrams provide the natural mathematical framework for the Attractor Flow Tree Formula, and give a global description of the BPS spectrum interpolating between orbifold points and large volume.  I will construct the scattering diagram for the simplest del Pezzo surfaces, namely the local projective space $K_{P^2}$ and local Hirzebruch surfaces $K_{F_0]$ and $K_{F_1}$, thereby completely characterizing the BPS spectrum in these examples. Based on [arXiv:2210.10712] in collaboration with Pierrick Bousseau, Pierre Descombes and Bruno Le Floch, and work in progress with Bruno and my student Rishi Raj.

Title: Supersymmetric index of small black holes

Abstract: We shall review recent progress towards computing supersymmetric index using gravitational path integral and apply this to compute the supersymmetric index of small black holes.
