Global existence and nonexistence of semilinear wave equation with a new condition
Bolys Sabitbek
In this paper, we consider the initial-boundary problem for semilinear wave equation with a new condition for some positive constants…
Global existence and blow-up of solutions to porous medium equation and pseudo-parabolic equation, I. Stratified Groups
Michael Ruzhansky, Bolys Sabitbek, Berikbol Torebek
In this paper, we prove a global existence and blow-up of the positive solutions to the initial-boundary value problem of the nonlinear porous medium equation and the nonlinear pse…
Global existence and blow-up of solutions to the double nonlinear porous medium equation
Bolys Sabitbek, Berikbol Torebek
In this study, we examine a double nonlinear porous medium equation subject to a novel nonlinearity condition within a bounded domain. First, we introduce the blow-up solution for…
Hardy and Rellich inequalities with Bessel pairs
Michael Ruzhansky, Bolys Sabitbek
In this paper, we establish suitable characterisations for a pair of functions on a bounded, connected domain in order to have the following H…
