Analytical Solution of Direct and Inverse Problems in the Internal Gravity Waves Studies by the Doppler Frequency Shift Method© 2018, Pleiades Publishing, Ltd. An analytical solution of direct and inverse problems arising

Decay of the solutions of the generalized Korteweg-de Vries equation at large timesIn this paper the existence of weak solutions of the nonlinear generalized KdV equation is shown

On the properties of solutions of a nonlinear filtration problem with a source and multiple nonlinearitiesOn the properties of solutions of a nonlinear filtration problem with a source and multiple

Analytical solution to a sea-water intrusion problem with a fresh water zone tapering to a triple pointA new explicit analytical solution is obtained to a steady-state abrupt interface problem

Smoothness of generalized solutions of a boundary-value problem for a second-order differential-difference equation with mixed boundary conditions-difference equation on a finite interval (0, d). We prove existence of a generalized solution of the problem and study
