Vertex algebra bicomplexes, continual Lie algebras, and reduction cohomology
Abstract:
The orthogonality and double grading conditions on the bicomplex structure of a vertex algebra cohomology endow it with the structure of a bigraded differential algebra with respect to a natural multiplication. Its generators and commutation relations form a continual Lie algebra with the root space associated to a vertex algebra, and provide non-vanishing cohomological invariants. We will introduce the notion of the reduction cohomology of Riemann surfaces in terms of vertex operator algebra n-point correlation functions. Algebraic, geometrical, and cohomological meanings of reduction formulas will be clarified.

Mathematical models of flow and heat transfer with mixed boundary conditions
Abstract:
In the lecture, we deal with some models of flow and heat transfer in incompressible fluids, e.g. the so-called complete system of the Navier-Stokes equations or the Boussinesq equations. We present some results for these models where we prescribe the mixed boundary conditions as the solvability of these models and other qualitative properties.
