In this seminar we shall discuss topics concerning constructions and applications of cohomology theory in algebra, geometry, physics and statistics. In particular we shall discuss in first four seminars the relations between vertex algebras and foliations on manifolds, Gelfand-Fuks cohomology on singular spaces, cohomology of homotopy Lie algebras. The expositions should be accessible for all participants.

Koszul algebras are a natural class of graded algebras with

quadratic relations, defined by a series of homological conditions.

To a Koszul algebra over with finite-dimensional components, one can

assign a one-dependent stochastic 0-1 sequence, which carries

information about the dimensions of the algebra's grading components.
