Mathematical modelling of random multicomponent systems

A joint research group.

The main aim of our research is to develop mathematical framework for the study of a class of stochastic systems of a large number of elements (called "particles") described by their "positions" and "marks" (representing internal structure of the corresponding particles). The particles are coupled via (random) interaction potentials.

Examples of systems of such type can be found in a wide variety of sciences, including quantum physics, astrophysics, chemical physics, biology, ecology, computer science, economics, finance, etc.
