## Current Research

One of the focuses of my study is to find the description of multiple M5-branes. It is supposed to be essential to describe the geometrical descriptions of dynamical symmetries found in various strongly coupled 4D system. One of such example is N=2 4D supersymmetric gauge theories, where such duality with 2D CFT was found.

In this case, we find quantum symmetry, which is equivalent to the extended higher spin symmetry (W-algebra) and manage to give an exact proof of the duality. We also have interest to find a new connection with the techniques of integrable models such as R-matrices, Dunkl operator and q-deformed algebras.
