Generalized $(\Lambda,b)$-closed sets in topological spaces

Chawalit Boonpok


A new class of sets, called generalized $(\Lambda,b)$-closed sets, has been introduced and studied. Also, several properties of generalized $(\Lambda,b)$-closed sets are investigated. Some characterizations of $\Lambda_b$-regular spaces and $\Lambda_b$-normal spaces are discussed.
