摘要
In this paper, we study some nonlinear parabolic equation involving p, m-Laplace operator with nonlinear source and boundary flux. First, we determine the critical curve of the existence of global solutions by constructing self-similar auxiliary functions. Second, the exponent region is proposed where every nontrivial solution blows up in finite time. In addition, blow-up phenomenon of the Fujita type is proved for the corresponding Cauchy problem of the nonlinear parabolic equation.
