Many problems of numerically solving the Schrodinger equation require that we choose asymptotic distances many times greater than the characteristic size of the region of interaction. The problems of resonance diffraction for composite particles or t

We propose a mathematical model of COVID-19 pandemic preserving an optimal balance between the adequate description of a pandemic by SIR model and simplicity of practical estimates. As base model equations, we derive two-parameter nonlinear first-ord

An algorithm based on direct discretization of a two-dimensional equation is proposed for numerically solving the problem of two-dimensional scattering. The asymptotic distance is reduced by presenting the solution as the sum of free waves. The usefu

In this paper, we propose a method that makes it possible to to improve energy reconstruction for data obtained via thin heterogeneous calorimeters for direct measurements of cosmic rays with energies of TeV and higher. Despite the large number of mo
