| Abstract: | 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. |
