摘要
给出了在K上的任意两个Banach空间之间,Fredholm映射在一个特定的开球中,至少有一个共同值的充分条件.结论的证明基于解析开拓法,并具有可构造性.
Sufficient conditions were given to assert that between any two Banach spaces over K, Fredholm mappings share at least one value in a specific open ball. The proof of the result is constructive and is based upon continuation methods.
