On Contra βθ-Continuous Functions


Miguel Caldas
Universidade Federal Fluminense, Brasil


In this paper, we introduce and investigate the notion of contra βθ-continuous functions by utilizing β-θ-closed sets. We obtain fundamental properties of contra βθ-continuous functions and discuss the relationships between contra βθ-continuity and other related functions.

2000 Mathematics Subject Classification : Primary 54C08, 54C10; Secondary: 54C05.

Keywords : β-θ-closed, βθ-continuous, contra βθ-continuous.
