Abstract:
For any additive subgroup M of a field F and α∈F such that 2α∈M, there are two classes of generalized super-Virasoro algebras denoted by SVir [M, α] and SVir^~ [M, α] by Su and Zhao. The latter is in fact a trivial extension of the former. In this paper, based on the discussion on isomorphisms, the Verma modules of Svir [M, α] are studied, and the irreducibility of these modules are obtained.
