Doubly nonlinear parabolic equations related to the p-Laplacian operator: Semi-discretization
Electronic Journal of Differential Equations, 2003 We study the doubly nonlinear parabolic equation $$ frac{partialBeta(u)} {partial t}-riangle_p u + f(x,t,u )= 0 quadhbox{in } Omegaimesmathbb{R}^+, $$ with Dirichlet boundary conditions and initial data.

On an Approximate Solution Method for the Problem of Surface and Groundwater Combined Movement with Exact Approximation on the Section Line [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2016 In this paper, the initial-boundary problem for two nonlinear parabolic combined equations has been considered. One of the equations is set on the bounded domain Ω from R2, another equation is set along the curve lying in Ω.

Finite element or Galerkin type semidiscrete schemes [PDF]
A finite element of Galerkin type semidiscrete method is proposed for numerical solution of a linear hyperbolic partial differential equation. The question of stability is reduced to the stability of a system of ordinary differential equations for which ...

Rothe's method for solving semi-linear differential equations with deviating arguments
Electronic Journal of Differential Equations, 2020 We consider a semi-linear differential equation of parabolic type with deviating arguments in a Banach space with uniformly convex dual, and apply Rothe's method to establish the existence and uniqueness of a strong solution.
