Quasi 𝒩-Open sets and related compactness concepts in bitopological spaces

Samer Al Ghour1 

Haneen Saleh1 

1Jordan University of Science and Technology, Department of Mathematics and Statistics, Irbid 22110, Jordan e-mail:


Three types of N-open sets are defined and investigated in bitopological spaces, and via them several compactness are introduced. Several relationships, examples and counter-examples regarding the new concepts are given.

Key Words and Phrases: ω-open set; N-open set; Compact; Countably Compact; Continuous Function
