In this paper, we consider the induced modules ∇ and the Weyl modules for the algebraic group G = SL(2, K) where K is an algebraically closed field of characteristic p > 0. We determine the G-modules H i (G 1 , ∇(s) ⊗ ∇(t)) for all i 0, where G 1 is the first Frobenius kernel of G. We then use it to
