Effect of temperature and magnetic field on the density of surface states in semiconductor heterostructures
Published 2024-12-01“…For the first time, a mathematical model has been developed to determine the temperature dependence of the density of surface states of a semiconductor under the influence of a strong magnetic field. Mathematical modeling of processes was carried out using experimental values of the continuous energy spectrum of the density of surface states, obtained at various low temperatures and strong magnetic fields, in the band gap of silicon. …”

ABOUT PLANE TRANSFORMATIONS THAT PRESERVE THE AREAS OF FIGURES
Published 2024-03-01“…The plane transformations, examined in this article, are essentisl to both fields, mathematics and economics. For a smooth transformation of the coordinate plane, is given a transformation represented by two functions of two variables with continuous first-order partial derivatives on the whole plane, so as a criterion is proved according to which this transformation is isoaric.…”

Vanishing viscosity method for transonic flow
Published 2008“…This formulation allows a family of invariant regions in the phase plane for the corresponding viscous problem, which implies an upper bound uniformly away from cavitation for the viscous approximate velocity fields. Mathematical entropy pairs are constructed through the Loewner-Morawetz relation via entropy generators governed by a generalized Tricomi equation of mixed elliptic-hyperbolic type, and the corresponding entropy dissipation measures are analyzed so that the viscous approximate solutions satisfy the compensated compactness framework. …”
