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. [...]
