g ∆ ∗ µ −closed sets in generalized topological spaces

In this paper, we introduce some new classes of generalized closedsets called ∆ ∗µ −g− closed, ∆∗µ −g µ − closed and g ∆ ∗ µ − closed sets, which are relatedto the classes of g µ − closed sets, g − λ µ − closed sets and λ µ − g− closed sets. Weinvestigate their properties as well as the relations among these classes of generalizedclosed sets.
