摘要:

该文主要利用单调迭代法和比较原理研究了带有指数型非线性项的离散泊松方程和带有指数型非线项的离散热方程解的存在性之间的关系,主要给出了带有指数型非线性项的离散泊松方程解存在时,带有指数型非线项的离散热方程解的渐近稳定性.

Abstract:

This paper mainly study the relations between the solution of the discrete Poisson equation and the solution of the discrete heat equation with exponential nonlinear term by monotone iterative method and comparison principle. When the solutions of the discrete Poisson equation exist, we discuss the asymptotic stability of the solutions to the discrete heat equation with exponential nonlinear term.

Key words: Discrete Poisson equation, Discrete heat equation, Graph, Comparison principle, Blow-up
