摘要

Let W (X, Y), Pwc (X, Y), CC (X, Y), and UC (X, Y) denote respectively the sets of all weakly compact, pseudo weakly compact, completely continuous, and unconditionally converging operators from X to Y. We use classical results of Kalton to study the complementability of the space W (X, Y) in the spaces Pwc (X, Y), UC (X, Y), and CC (X, Y).
