Title: On the non-renormalization of supercharge Q-cohomology

Abstract:  In a quantum system with a complex nilpotent supercharge Q, one of the most basic problems is the cohomology of Q, and how it varies in the space of theories. I will discuss a conjecture on the non-renormalization of the Q-cohomology, evidence for it in various examples, and applications in holography.

Title: Quantum Corrections in Near-Extremal Black Holes: Thermodynamics, Dynamics and Applications

Abstract: I will revisit the  low-temperature thermodynamics of near-extremal  rotating black holes that has recently been shown to incorporate quantum contributions that are dominant in this regime. I will also describe how these quantum fluctuations affect the spectrum of emission of particles during Hawking radiation. In particular, I will consider the cases of Kerr and Kerr-Newman black holes for emission of scalar particles and discuss photon and graviton emission from the Kerr background. I will also comment on potential implications for the AdS/CMT correspondence approach to strange metals.

Title: Symmetries, operators and correlators in TTbar deformed CFTs

Abstract: $T\bar T$ deformations are solvable irrelevant deformations of quantum field theories in two dimensions. Such deformations preserve lots of interesting properties of the seed theory,  and can be used to understand holographic dualities beyond the AdS/CFT correspondence. In this talk, I will show how conformal symmetries are realized in $T\bar T$ deformed CFTs, how they can be used to organize states and operators, and how they facilitate the computation of correlation functions.

Title: Perturbatively exact supersymmetric partition functions of ABJM theory on Seifert manifolds and holography

Abstract: I will introduce the supersymmetric partition function of ABJM theory on a U(1) fibration over a Riemann surface, evaluating it to all orders in the 1/N-perturbative expansion up to exponentially suppressed corrections via the Bethe formulation. Through holographic duality, this result is matched with the regularized on-shell action of a dual Euclidean AdS4-Taub-Bolt background incorporating 4-derivative corrections, and also provides valuable insights into the logarithmic corrections that emerge from the 1-loop calculations in M-theory path integrals. In this process, I will also revisit the Euclidean AdS4-Taub-Bolt background carefully, elucidating the flat connection in the background graviphoton field. This analysis unambiguously determines the U(1)R holonomy along the Seifert fiber, thereby solidifying the holographic comparison regarding the partition function on a large subclass of Seifert manifolds.

Title: One volume to rule them all... and in the darkness localize them Dario.pdf

Abstract: Over the past two decades, a range of extremal problems arising in geometry, supergravity, black holes, and quantum field theory have been found to involve certain generalized volume functionals. Recent developments have revealed two interconnected advances. First, in 2309.04425 we have proposed that these generalized volumes can all be derived from a single object: the equivariant volume, which can be evaluated concretely via the technique of equivariant localization. Second, again employing equivariant localization (in odd dimensions), in 2502.15624 we have shown that the regularised on-shell action for a broad class of supersymmetric solutions of D=5 gauged supergravity — including the well-known Kerr-Newmann black holes in AdS₅ — can itself be written as a generalized volume functional. This unified perspective offers a powerful framework for understanding the geometric underpinnings of supersymmetric field theories and gravitational solutions.

Title: Supersymmetric Configurations Extended Higher Derivative Supergravity in four dimensions Bindusar.pdf

Abstract:Conformal supergravity provides a powerful off-shell framework for analyzing supersymmetric solutions in higher-derivative supergravity theories. This approach was employed by Cardoso et al. (hep-th/0009234) to classify all stationary supersymmetric solutions in higher-derivative N=2 supergravity in four dimensions. Their analysis revealed that both AdS2×S2 and flat space preserve the full N=2 supersymmetry, while extremal black holes preserve only a residual N=1 supersymmetry.

In this talk, we will begin with a brief review of their work and then present our recent results (arXiv:2505.00638), where we extend the classification to fully supersymmetric solutions in higher-derivative N=3 and N=4 supergravity in four dimensions, again utilizing the conformal supergravity framework. Our findings indicate that, unlike the N=2 case, these extended supergravity theories admit only flat space as a fully supersymmetric solution.

We will also discuss the underlying reasons for the richer structure of supersymmetric vacua in N=2 compared to N=3 and N=4, focusing on key differences in their auxiliary field content and multiplet structure. We will conclude with an overview of our ongoing work aimed at classifying half-BPS and quarter-BPS solutions in N=4 supergravity.
