Structural unit: Faculty of Science.
The laboratory’s work is aimed at developing qualitative research methods for nonlinear and nonlocal equations. The laboratory was opened thanks to the victory in the megagrant of the national project “Science and Universities”. The team of S. M. Nikol’skii Mathematical Institute of RUDN University, led by S. B. Kuksin, a leading scientist in the field of partial differential equations and their applications to mathematical physics, received support.

A mathematical model of respiratory viral infections in cell cultures and body tissues has been developed to study the effect of the immune response on the rate of infection spread and viral load. This makes it possible to predict scenarios of the course of the disease depending on the initial viral load and the parameters of the immune response. The assessment of the duration of the disease was studied using real data on COVID-19. These results are important for epidemiologists, immunologists, and physicians and will allow them to predict the spread of viral infections, in particular COVID-19.
A computer program has been developed to simulate the current distribution in a weakly ionized plasma of vaporized tungsten. The simulation results obtained with its help have been tested at a number of leading international conferences on mathematical physics.
The first mathematical model of plasma confinement in a spiral magnetic field has been developed. This is necessary to prevent the plasma from cooling down or the reactor from collapsing due to the ingress of a large number of plasma particles.
