Anti $ T_{2} $-generalized topological spaces

Abstract

In this paper, we investigated non strong hyperconnected generalized topological spaces. Ekici \cite{Eki11} and Devi \cite{Ren12} have provided the results of hyperconnectedness for strong generalized topological spaces. We generalized these results for arbitrary generalized topological spaces. Through the notion of hyperconnectedness of arbitrary generalized topological spaces, we constructed an example which fails Hausdorff characterization of topological spaces \lq\lq A first countable spaces is Hausdorff if and only if every convergent sequence has unique limit\rq\rq. This example also serves the purpose of constructing Anti Hausdorff Fr$\acute{e}$chet space in which every convergent sequence has unique limit required by Novak in \cite{Nov39}.
