The theorems of Glicksberg and Hurwitz for holomorphic maps in complex Banach spaces
The aim of this paper should be a generalization of Glicksberg's and Hurwitz's theorems concerning the number of zeros of holomorphic maps to infinite-dimensional Banach spaces. Unfortunately, the assumptions of Theorem 2.2 (Hurwitz Theorem for Banach spaces) come true only in finite- dimensional Banach spaces.
