Shaposhnikov Stanislav Moscow State University, Moscow, Russia «Fokker-Planck-Kolmogorov Equations: Changes of Coordinates»
Fokker-Planck-Kolmogorov equations play a key role in the investigation of diffusion processes. Transition probabilities and stationary distributions of diffusion processes are solutions of the equations. In the case of irregular coefficients it allows to study qualitative properties of transition probabilities and stationary distributions, to construct a diffusion process, and to obtain results of diffusion process’s uniqueness. Latest achievements of the theory of Fokker-Planck-Kolmogorov equations relate to a usage of few nontrivial changes of coordinates, such as: Zvonkin's transform, the method of doubling variables, and different methods of the renormalization of solutions. In the lecture course we consider these transforms and give recent results, which are obtained with their help. |

Gomoyunov Mikhail Krasovskii Institute of Mathematics and Mechanics UB RAS, Yekaterinburg, Russia «Minimax and Viscosity Solutions of Path-Dependent Hamilton-Jacobi Equations» In the lecture course, recent results from the theory of minimax and viscosity (generalized) solutions of path-dependent Hamilton-Jacobi equations with coinvariant derivatives over the space of continuous functions will be presented. Equations of this type arise in dynamical optimization problems for time-delay systems. The first lection will cover classical results from the theory of minimax and viscosity solutions of Hamilton-Jacobi equations with first-order partial derivatives. In the second lection, we will see how these results are generalized to the (infinite-dimensional) case of path-dependent Hamilton-Jacobi equations. |

Hu Guang-Da Department of Mathematics, Shanghai University, Shanghai, China «Difference Stabilizing Controller of Linear Delay Systems» This lecture course investigates stabilization of linear delay systems. A difference stabilizing controller is designed for linear delay systems. The first lecture covers stability criteria which includes frequency-domain and time-domain methods. The second lecture involves design of the difference stabilizing controller which includes existence of the difference stabilizing controller and designing methods of the controller. Both theoretical results and numerical algorithms are provided. Several numerical examples are given to illustrate the theoretical results and the numerical algorithms.
