“…It plays a very important role in mathematics and physics. The structure and representation theories of (generalized) super-Virasoro algebra have been extensively undertaken by many authors [1,3,[11][12][13][14][15][16][17]. The generalized super-Virasoro algebra SVir[Γ, s] is a Lie superalgebra whose even part 0 SV has a basis {L α , C|α∈Γ} and odd part 1 SV has a basis {G µ |µ∈Γ+s}, equipped with the following Lie superbrackets: In the present work, we will consider the following Lie superalgebra, called not-finitely graded generalized super-Virasoro algebra [Γ, s], which has a basis {L α,i , G µ,j ||α∈Γ,µ∈s+Γ,i, j∈+}, and satisfies the following relations:…”
