关于Burgers-Fisher方程平衡解的分岔问题(英文)

当参数λ在临界值λk=k2(k=1,2,…)附近且小于它时,利用Liapunov-Schmidt方法在奇函数空间H1中得到了两个严格的非平凡定态解,在整个空间H1中得到了一个分岔圆.     

DIFFERENTIABILITY FOR THE HIGH DIMENSIONAL POLYNOMIAL-LIKE ITERATIVE EQUATION

This paper studies the smoothness of solutions of the higher dimensional polynomial-like iterative equation. The methods given by Zhang Weinian^[7] and by Kulczycki M, Tabor J.^[3] are improved by constructing a new operator for the structure of the equation in order to apply fixed point theorems. Existence, uniqueness and stability of continuously differentiable solutions are given.
