摘要 我们探讨了n种群互惠系统,进而得到了互惠系统周期解的存在性的充分条件.我们的方法是基于Mawhin重合度,矩阵的谱理论和对算子方程Lx=λNx一些新的先验界估计. In this paper, we studied the famous periodic mutualism system. Some new and interesting sufficient conditions are obtained to guarantee the existence the periodic solution in the mutualism system. Our method is based on Mawhin' s coincidence degree, matrix' s spectral theory and some new estimation techniques for the priori bounds of un - known solutions to the equation.
