Let T be an operator of class C 0 and M be an invariant subspace for T. We find a relationship that must hold for the Jordan models of T, T | M and T \* | M = . This relationship reduces to a theorem of Green when T is algebraic, and it involves a continuous extension of Littlewood Richardson sequen
