Abstract Fuzzy topology was developed by many authors. The intuitionistic fuzzy sets were introduced by Atanassov (1986) as a generalization of fuzzy sets by L. A. Zadeh (1965). The paper is therefore addressed to the introduction of the concept of base, sub-base, subspace, closure, interior and quasi neighbourhood in intuitionistic fuzzy topology developed by Kumar and Das (2019).
