| Let G=SL( l+ 1 , K) be a simply connected, semi-simple algebraic group of type A1 over an algebraically closed field of characteristic p > 0. In this paper, we give a complete description of Weyl filtration quotients of tensor products of the form V(mλ1)(?)V(λ); some isomorphisms between such tensor products and its quotients are established.We get also some Ext1 groups for irreducible G modules . |
