摘要 本文利用锥映象不动点指数计算方法,结合极值原理、上下解方法以及算子的谱分析,得出了一类反应扩散方程非负平衡解的存在性。 In this paper, by means of calculating the indices of fixed points of compact maps in cones, in combination with the maximum principles, lower-upper solutions methods and spectrum analysis of operators, we consider the coexistence of steady states for a kind of reaction-diffusion systems.
