Data-driven algorithms. Dynamical systems.

Numerical analysis and numerical methods for differential and integral equations, including data-driven numerical algorithms. The most effort is placed on the development of structure-preserving numerical methods for the study of dynamical systems with applications, for example, Hamiltonian dynamics, crystal lattice models of molecular dynamics, nonlinear waves in crystals, localization, un dynamical systems machine learning.

Mathematical modelling of diffusion and flow problems, optimization of parameters and solution patern recognition

Mathematical modelling of diffusion and flow problems with partial differential equations involves the use of mathematical equations to describe the behavior of complex systems. Identifying and optimizing parameters, as well as recognizing the solution patterns. The usage of initial and boundary-value problems for systems of partial differential equations to model how substances or particles diffuse and react with each other within a given medium, and then finding ways to optimize these equations for better predictions. Identifying patterns in the solutions obtained through the optimization process to better understand the underlying mechanisms of diffusion and reaction.
