In this paper, we apply the notion of $\beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $\beta^{*}$-continuous and almost contra $\beta^{*}$-continuous functions as a new generalization of contra continuity.https://scma.maragheh.ac.ir/article_22045_9b9885af1b47833c61470ac4706d0a25.pdf
