  "abstract": "Given three normed spaces $X_0 , X_1 , \\tilde{X_1}$, with $\\tilde{X_1}$ a closed subspace of $X_1$ with same norm, how does $[X_0 , X_1 ]_\\theta$ compare to $[X_0 , X_1 ]_\\theta ? This classical problem of interpolation theory has been mostly considered in the case of finite codimensional subspaces. We show here that quotient J norms are a useful tool which allows to tackle several relevant cases.",
