Abstract

In this paper, we present a class of parabolic equation with nonlinear where we show two part of this study the theoretical part we prove the existence and uniqueness of the solution by energy inequality method. Then we present finite time blow up by using the energy method.

Summary

Introduction

Partial differential equations play an important role in modeling many disciplines including engineering, physics, chemistry economics, and biology, and their study has occupied mathematicians since the eighteenth century with the work of Euler, D’Alambert, Lagrange, and Laplace...; over the last forty years many modern physical, mechanical, biological and technological phenomena, and problems have been shaped by partial differential equations (PDEs), many physical phenomena are modeled by nonclassical parabolic problems associated with boundary conditions. As the first question to be asked in the theoretical study is to know if, for a nonlinear evolution equation with initial conditions and boundary conditions, there exists at least one local solution and if it is unique in the case considered, these problems have been solved for a large class of nonlinear evolution equations by a series of useful. There are many works focused on the blow-up property of various parabolic equations (or systems) with homogenous Newmann boundary conditions
