Abstract

This paper studies various completeness properties of the open-point and bi-point-open topologies on the space C(X) of all real-valued continuous functions on a Tychonoff space X. The properties range from complete metrizability to the Baire space property.

Key words and phrases

point-open topology open-point topology bi-point-open topology completely metrizable Čech-complete locally Čech-complete sieve-complete partition-complete pseudocomplete Baire space
