PUMPING EFFECT IN THE THEORY OF NONLINEAR PROCESSES OF THE THERMAL CONDUCTIVITY EQUATION TYPE AND ITS APPLICATION IN GEOPHYSICS

Abstract

Many natural processes are described by nonlinear parabolic equations of the thermal conductivity equation type, in which the coefficient of the medium is a function of the value sought. Although the class of these equations is called equations of thermal conductivity, they are used in the description of absolutely different processes.
