摘要:

考虑具有指数三分性的线性微分方程伪几乎自守解的存在性, 应用LeraySchauder不动点定理证明了对于非线性方程x′(t)=f(t,x](t))+g(t,x(t)), 当f和g[WT]均为伪几乎自守时存在伪几乎自守解.

关键词: 指数三分, 伪几乎自守, 不动点

Abstract:

The authors dealt with the existence of pseudoalmost automorphic solutions to the linear differential equation which has an exponential trichotomy, and the result  also holds for nonlinear equations  x′(t)=f(t,x(t))+g(t,x](t)) by means of the application of LeraySchauder fixed point theorem, where f,g are pseudoalmost automorphic functions.

Key words: exponential trichotomy, pseudoalmost automorphic, fixed point
