Abstract

‎In this paper‎, ‎we introduce the complex (anti complex) fuzzy topological space $(X‎, ‎\mathfrak{T})$‎ ‎with complex (anti complex) gradation of openness under $T$-norm ($C$-conorm) which $X$ is itself a $T$-complex ($C$-anti complex) fuzzy subset of a nonempty set $M$‎. ‎We show that the set of all $T$-complex gradations of openness on $X$ is a semicomplete lattice‎. We give some example such as $T$-complex fuzzy subspace of $\Lambda \mathbb{R}^{m}$‎, ‎the exterior algebra on $\mathbb{R}^{m}$.
