BLOW-UP SOLUTIONS TO DEGENERATE PARABOLIC EQUATIONS WITH NONLOCAL BOUNDARY
摘要
Abstract
In this paper,we consider the weak solutions of the degenerate parabolic equations coupled via nonlocal sources,subject to nonlocal boundary conditions. By using the comparison principle,the critical blow-up exponent is obtained under the help of the weighted functions and the initial data. Moreover,asymptotic behavior near blow-up time is obtained for simultaneous blow-up solutions,which extends the known results in the previous paper.关键词
