On the solution to a two-dimensional boundary value problem of heat conduction in a degenerating domain

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
The article considers a homogeneous boundary - value problem for the heat equation in the non - cylindrical domain, namely, in an inverted pyramid with a vertex at the origin of coordinates, two faces of which lie in coordinate planes.A solution to the ...

Boundary-value problems for a third-order loaded parabolic-hyperbolic equation with variable coefficients

open access: yesElectronic Journal of Differential Equations, 2015
We prove the unique solvability of a boundary-value problems for a third-order loaded integro-differential equation with variable coefficients, by reducing the equation to a Volterra integral equation.
