Biswanath Garai,Chhanda Bandyopadhyay 경북대학교 자연과학대학 수학과 2004 Kyungpook mathematical journal Vol.44 No.3
Defining a new type of set called I-set we have characterized those sets. A sufficient condition have been given so that any two nonempty I-open sets intersect in a nonempty I-open set.
I-Dense Sets and I-o.h.i. Spaces
