N. Rajesh, Jamal Mustafa


In this paper, we introduce and study the notion of (i, j)-w-preopen sets as a generalization of (i, j)-preopen sets in bitopological space.

Palabras clave

Bitopological spaces; (i,j)-preopen sets; (i,j)-precontinuous functions; espacios bitopológicos; conjuntos (i,j)-preabiertos; funciones (i,j)-precontinuas.
