$\gamma^{*}$-semi-open Sets in Topological Spaces-II
  In this paper, we continue studying the properties of $\gamma^{*}$-semi-open sets in topological spaces introduced by S. Hussain, B. Ahmad and T. Noiri[8]. We also introduce and discuss the $\gamma^{*}$-semi-continuous functions which generalize semi-continuous functions defined by N. Levine [10].
