Representations of the Witt superalgebra W(2)W(2)

In this paper, we study representations of the Lie superalgebra W(2)W(2) of Witt type over an algebraically closed field of characteristic p>2p>2. All irreducible modules and their dimensions are determined, up to isomorphisms. Thus, all irreducible modules and their dimensions of osp(2|2)osp(2|2) are determined in prime characteristic, up to isomorphisms.
