Resurgence and non-perturbative topological strings
/ Marino Beiras, Marcos (speaker) (University of Geneva, Switzerland)
The string perturbative series diverges factorially, and it is expected that this behavior is related to the existence of non-perturbative effects due to D-branes. Although these ideas can be made precise in the case of non-critical strings, little is known in other situations. [...]

Quantum Entanglement Entropy in String Theory
/ Dabholkar, Atish (speaker) (ICTP)
I discuss physical motivations from black hole physics and holography for expecting finite quantum entanglement entropy in quantum gravity. I describe recent and earlier results in defining such a notion in perturbative string theory by a stringy analog of the replica method using ZN orbifolds constructed for any odd positive integer N. [...]

A Holographic Triptych at Large N
/ Bobev, Nikolay (speaker) (KU Leuven)
I will summarize recent results, obtained using supersymmetric localization, about the large N limit of path integrals of 3d SCFTs arising on the worldvolume of N M2-branes placed on compact Euclidean manifolds. The leading N^3/2 term in the large N expansion of these "free energies" receives 1/N, log(N), as well as exponentially suppressed corrections. [...]

Bootstrapping the AdS Virasoro-Shapiro amplitude
/ Hansen, Tobias (speaker) (Durham University , UK)
The formulation of the worldsheet theory for type IIB strings on AdS5xS5 remains an important open problem. Luckily, at least the corresponding AdS Virasoro-Shapiro amplitude can be bootstrapped in a small curvature expansion. [...]

Recent developments in Generalized Symmetries
/ Schafer-Nameki, Sakura (speaker) (University of Oxford, UK)
I will review recent progress on generalized symmetries, focusing on non-invertible (or higher categorial) symmetries and their properties.
Two questions have recently been the focus in this subject: What replaces the notion of "representation" for group-like symmetries, i.e. what are the generalized charges? What are the IR imprints of non-invertible symmetries? To answer these questions, it is crucial to study the Symmetry Topological Field Theory (SymTFT), which has close relations to string theoretic and holographic realizations of generalized symmetries. [...]

Quantum Gravity and Predictions for our Universe
/ Vafa, Cumrun (speaker) (Harvard University)
In this talk I provide an executive summary of some of the recent progress that has been made in understanding some key features of quantum gravitational theories. This is rooted in lessons learned from the landscape of consistent solutions to string theory and captured by the principles of the Swampland program [...]
