Piotr Kucharski (IFT UW)BPS spectra and BPS quivers
In this talk I will briefly present the relation between the spectrum of BPS states in 4D N=2 quantum field theories and a notion of BPS quiver. I will present how to construct such an object knowing all BPS states and (what is more interesting) how to obtain BPS spectrum from BPS quiver. My talk will be based on the paper "N=2 QFT and Their BPS Quivers" [1112.3984].

Helder Larraguivel (IFT UW)Quantum Airy structures and topological recursion
A few years ago, in the context of matrix models a powerful recursion relation was introduced to compute asymptotic expansion of random matrix integrals. Then it was extended axiomatically to other integrable systems, which turn out to yield various geometric invariants, like Gromov-Witten invariants and knot polynomials. This method has given many new results in enumerative geometry, random surfaces, quantum curves and many more. Very recently the topological recursion was found to be a particular case of a deformation quantization procedure, and the notion of quantum Airy structures has been introduced. So, in this presentation I will talk about how an Airy structure is defined as a Lagrangian obeying certain commutation relations. Also, I will show how the recursion relation arises as a solution to a family of Schroedinger equations and discuss some symmetries and properties of the Airy structures.

Marithania Silvero (IMPAN)How to compute Khovanov homology
Khovanov homology is a powerful invariant introduced by Mikhail Khovanov in 2000. This link invariant, which categorifies Jones polynomial, was nicely reinterpreted by Viro in a purely combinatorial way in terms of Kauffman states. In this introductory talk we will review the main properties of Khovanov homology, starting from this combinatorial construction, and presenting some explicit examples. Moreover, in the second part of the talk I will present our geometric realization of extreme Khovanov homology in terms of a simplicial complex constructed from the independence graph associated to a link diagram.

Marcin Piątek (University of Szczecin)2d CFT, N=2 gauge theories and solvable spectral problems
The so-called 2d/4d correspondences connect two-dimensional conformal field theory (2d CFT), N=2 supersymmetric gauge theories and quantum integrable systems. The latter in the simplest case of SU(2) gauge group are just quantum–mechanical systems. During seminar it will be shown how these dualities can be used, in particular, to study the spectra of Schroedinger operators with periodic (Hill's), PT-symmetric and elliptic (finite-gap) potentials. Moreover, it will be mentioned that an application of 2d CFT technics and tools such as (classical) conformal bootstrap paves the way for studying nonperturbative effects in afforementioned quantum-mechanical systems. Finally, some open problems such as the relation to the KdV theory will be mentioned as well
