The aim of this paper is to study the α-semi-Fredholm operators in a nonseparable Hilbert space H for all cardinals α with . In the first part, we find the relation between and for all -regular cardinals α, where is the reduced minimum modulus of weight α, c is the reduced minimum modulus (in a C*-algebra) and is the canonical surjection from B(H) onto . We study the continuity points of the maps and . In the second part, we prove some approximation results for semi-Fredholm...
