A Generalized Topological Degree in Admissible Linear Spaces

T. Okon[1]

(1) Technische Universität Dresden, Germany

The paper deals with the construction of a degree which extends the Generalized Topological Degree of Browder and Petryshyn to admissible linear spaces introducing the notion of approximation nets and approximation-compact maps. After discussing the usual properties of a degree the relationship between approximation compactness and the concept of condensing maps is analysed.

Keywords: Admissible spaces, topological degree, condensing maps
