Space dimension can prevent the blow-up of solutions for parabolic problems

open access: yesElectronic Journal of Differential Equations, 2007
In the present paper, we investigate the preventive role of space dimension for semilinear parabolic problems. Conditions guaranteeing the absence of the blow-up of the solutions are formulated.

Existence of solutions for a non-variational system of elliptic PDE's via topological methods

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we prove the existence of solutions for a non-variational system of elliptic PDE's. Also we study a system of bi-Laplacian equations with two nonlinearities and without variational assumptions.

Parabolic Nonlinear Second Order Slip Reynolds Equation: Approximation and Existence

open access: yesNonlinear Analysis, 2007
This work studies an initial boundary value problem for nonlinear degenerate parabolic equation issued from a lubrication slip model. Existence of solutions is established through a semi discrete scheme approximation combined with some a priori estimates.

ε-Аpproximation of the temperatures model of inhomogeneous melts with allowance for energy dissipation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
Accumulated facts and information about the Navier-Stokes equations, together with a large number of experiments and approximate calculations, made it possible to reveal some discrepancies between the mathematical model of a viscous melt and real ...

On stability of nonlinear difference equations and some of their applications

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The issues of stability in solving nonlinear difference equations were considered. Based on a generalized difference analog of the well-known Bihari lemma, stability conditions for a trivial solution based on initial data were obtained, and an a priori ...
