摘要
We prove that if is a real Banach space, with , which contains a subspace of codimension 1 which is 1-complemented in and whose group of isometries is almost transitive then is isometric to a Hilbert space. This partially answers the Banach-Mazur rotation problem and generalizes some recent related results.
