摘要:

该文研究了无穷维Banach流形M,S,N间的Fredholm映射F(u,s):M×SN的广义横截性定理. 如果映射F(u,s)广义横截于单点集{θ^}, 而且fs(u)=F(u,s)在外部参数s的意义下是Fredholm映射, 那么必然存在一个剩余集ΣS,使得对于任意的sΣ, fs(u)都广义横截于{θ^}.

Abstract:

Generalized transversality theorem for Cr mapping F(u,s):M×SN is established in infinite dimensional Banach manifolds M,S,N. If the mapping F(u,s) is generalized transversal to a single point set {θ^}, and fs(u)=F(u,s) is a Fredholm operator in the sense of parameter s, then there exists a residual set ΣS, such that fs(u) are generalized transversal to {θ^}, for all sΣ.

Key words: Transversality, Generalized inverse, Banach manifold, Singularities
