摘要
用上、下解方法证明了一类二阶非线性方程组周期边值问题解的存在性,并给出迭代格式,为解的近似计算提供算法。在某种意义下为求反应扩散方程的周期行波解提供一种方法。
The existence of solutions for a class of second order nonlinear periodic boundary value problems using the upper and lower solution method is discussed . One iterative format is given for the calculation of approximate solutions . And monotone method is given for solving the periodic travelling wave solutions of reaction - diffusion systems .
