<b>µ β generalized α closed sets in generalized topological spaces</b> In this paper, we have introduced a new class of sets in generalized topological spaces called µ ß generalized a closed sets. Also we have investigated some of their basic properties. Generalized topology, generalized topological spaces, µ a closed sets, µ ß generalized a closed sets 2318-2320 Issue-3 Volume-2 Kowsalya M | Jayanthi D
