• SEMI - PRE R1 AND WEAKLY SEMI-PRE R0 SPACES

Dr. N. BANDYOPADHYAY*, Prof. P. BHATTACHARYYA

Abstract


In this paper we introduce sp-R1 and weakly –sp- R0 space with the help of semi-preopen sets defined by Andrijevic/[1]. Semi-pre θ-closure of a set is defined and used to investigate basic properties of sp-R1 space. Some results on invariance and productivity of   weakly - sp- R0 spaces have been obtained.

Keywords


sp-ker, sp-R1, weakly sp- R0.
