Basker Laboratory of Information Processing, Faculty of Science Ben M’Sik, University Hassan II, Casablanca, Morocco Broumi Said In this paper, we have introduced the concept of nk#Nα (n1 ) by using CLN α({n1}) where n1∈ N via Nα-open sets. Also we have introduced the spaces called Nψα# 0-space and Nψα# 1-space. 2021 2021 09 15 10.54216/IJNS.160101
