Linear topological classifications of certain function spaces. II.
Some properties of
Generalized tri-quotient maps and Čech-completeness
For a topological space let be the set of all compact subsets of . The purpose of this paper is to characterize Lindelöf Čech-complete spaces by means of the sets . Similar characterizations also hold for Lindelöf locally compact , as well as for countably -determined spaces . Our results extend a classical result of J. Christensen.
