In this paper, we study the zero-dimensional and one-dimensional cohomologyof sl2 with coe?cients in the Cartan type modular Lie superalgebras W(m,n,1).Let K be an algebraically close field of prime characteristic p > 2, W(m,n,1) bethe generalized Witt type modular Lie superalgebras. By definition, W(m,n,1) isa sl2-module. In Chapter 2 give the direct sum decomposition of irreducible sl2-submodule of W(m,n,1). For the cohomology of sl2 with coe?cients in W(m,n,1)is isomorphic to the direct sum of the cohomology of sl2 with coe?cients in eachirreducible submodule of W(m,n,1). Using the definitions of zero-dimensional andone-dimensional cohomology, in Chapter 3 we calculate all the zero-dimensional andone-dimensional cohomology of irreducible submodules of W(m,n,1), respectively.Thus we given structure of H0(sl2,W(m,n,1)) and H1(sl2,W(m,n,1)). This papergives the results of the low-dimensional cohomology of sl2 to a class of complexmodules. The author expects to provide a useful reference of cohomology of sln-module and gln-module for a further investigation. |
