Blow-up for a non-Newtonian Polytropic Filtration Equation with Multiple Nonlinearities
This paper deals with the global existence and blow-up of a non-Newtonian polytropic filtration equation with multiple nonlinearities. We obtain necessary and sufficient conditions on the global existence of all positive solutions by constructing super solutions and sub solutions. AMS Subject Classifications: 35K50, 35K55, 35K65.
متن کاملBlow-up for a reaction-diffusion equation with variable coefficient
We study the blow-up behavior for positive solutions of a reaction–diffusion equationwith nonnegative variable coefficient. When there is no stationary solution, we show that the solution blows up in finite time. Under certain conditions, we then show that any point with zero source cannot be a blow-up point. © 2012 Elsevier Ltd. All rights reserved.

متن کاملA fast iterative solver for the variable coefficient diffusion equation on a disk
We present an efficient iterative method for solving the variable coefficient diffusion equation on a unit disk. The equation is written in polar coordinates and is discretized by the standard centered difference approximation under the grid arrangement by shifting half radial mesh away from the origin so that the coordinate singularity can be handled naturally without pole conditions. The resu...
متن کاملThe smoothed particle hydrodynamics method for solving generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system
A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...
