# Applied Maths Seminar: Gaitsgory -- Occupational measures approach to analysis of non-linear controlled dynamical systems

We will discuss an asymptotic behaviour of the set of occupational measures generated by
a non-linear controlled dynamical system, and we will show that, as the time horizon
goes to infinity, this set is approaching to a convex and compact set characterized by
linear constraints.  We will use the fact of such a convergence for analysis and
solution of long-run average problems of optimal control and for approximating of the
slow dynamics of singularly perturbed control systems.  Theoretical developments will be
illustrated by numerical examples.  The presentation will be based on new results as
well as on earlier results published in
