Title : Hairy AdS black holes
Abstract : I will explain the recent constructions of hairy AdS black holes and suggest resolutions of some puzzles on these objects in the past. For supersymmetric hairy black holes, we quantitatively test their existence from the dual SCFT.

Title : Chiral algebra, Wilson lines, and mixed Hodge structure of Coulomb branch
Abstract : In the talk we will discuss an intriguing relation between the chiral algebra and the mixed Hodge structure of the Coulomb branch of four dimensional N = 2 superconformal field theories. Using Wilson line operators and modularity, one can compute characters of modules of VOAs corresponding to class-S theories. One can then check that the representation information is also encoded into the pure part of the mixed Hodge structure of the Coulomb branch of the same theory. This provides more relation between the Higgs and Coulomb branch of 4d N=2 theories, expanding the scope of 4d mirror symmetry.

Title : A 2d/2d unitary/non-unitary correspondence, Part I
Abstract : We introduce a correspondence relating the S^2 partition functions of certain 2d N=(2,2) theories to correlators of non-unitary 2d CFTs. Similarly to AGT, we begin with a 4d N=2 SCFT on S^2 x Sigma, with Sigma a punctured Riemann surface: a topologically twisted reduction on Sigma yields the (2,2) theory on S^2, while reducing on S^2 produces the CFT on Sigma. The chiral algebra of the resulting CFT is equal to the VOA of the parent 4d SCFT, thereby extending the SCFT/VOA correspondence to a full CFT. We outline the framework and illustrate it with free theories and Argyres-Douglas SCFTs related to minimal models.

Title : A 2d/2d unitary/non-unitary correspondence, Part II
Abstract : Dimensional reduction often implies non-trivial connections between field theories in different dimensions. A well-known example is the AGT (Alday-Gaiotto-Tachikawa) type relation that connects partition functions of different theories sharing a common higher dimensional ancestor. In this talk we shall exploit this relation to study the compactification of the 4d H0 SCFT on Riemann surfaces to get 2d (2,2) theories. Specifically, we shall argue for a 2d/2d unitary/non-unitary correspondence of AGT type between the resulting 2d theories and the Lee-Yang minimal model. We use this to identify the resulting 2d theories for certain choices of the Riemann surfaces, and test them with a variety of consistency checks.

Title : Cardy limit of superconformal indices in d=3,4
Abstract : We review recent progress on Cardy limit of the 4d superconformal index and its connection with supersymmetric gauge dynamics on R^3xS^1. We also present new results on Cardy limit of the 3d superconformal index, highlighting in particular the emergence of punctured surfaces in the problem and their competition with punctures in setting the asymptotics.

Title : Interplay of Generalized Symmetries and Moduli Spaces in 3d N=5 SCFTs
Abstract : 3d N=5 SCFTs possess a rich structure, and in this talk, I'll discuss the intricate relationship between their generalized symmetries and their moduli spaces. We'll focus on the orthosymplectic ABJ theories as our main case study. It is known that N=5 moduli spaces can be described as orbifolds H^{2N}/Gamma, where Gamma is a quaternionic reflection group. But what happens when we consider more exotic gauge groups like Spin, O^-, or Pin? I'll show that the story gets richer: the space is instead governed by a Z_2 central extension of Gamma, and I'll show you exactly how to build it. This leads to a key question: if we gauge a Z_2 zero-form symmetry, how does the moduli space change? I'll present a systematic recipe for this, showing how to get the new group Gamma' by simply adding a new generator to Gamma. We'll also discuss how 't Hooft anomalies for these zero-form symmetries manifest in both the superconformal index and the moduli space. Finally, we'll revisit the symmetry webs of the so(2N)_{2k} x usp(2N)_{-k} theories, covering all possible parities of N and k. Time permitting, I'll also touch upon theories with unequal ranks, the so(2N+1) algebra, and the two SCFT variants based on the F(4) superalgebra.
