Quotients of L1 by reflexive subspaces. Manuel González, Antonio Martínez-Abejón (1997) Extracta Mathematicae Here we present and example and some results suggesting that there is no infinite-dimensional reflexive subspace Z of L1 ≡ L1[0,1] such that the quotient L1/Z is isomorphic to a subspace of L1.
