A version of the Lomonosov invariant subspace theorem for real Banach spaces Gleb Sirotkin 47A15invariant subspacescomplexification It is known that for real Banach spaces the famous Lomonosov Invariant Subspace Theorem may fail. In our paper we will give a complete characterization of operators on real Banach spaces for which this theorem holds true.
