[Banach] Abstract of a paper by Stanislaw J. Szarek and Nicole Tomczak-Jaegermann

This is an announcement for the paper "On the nontrivial projection problem" by Stanislaw J. Szarek and Nicole Tomczak-Jaegermann.

Abstract: The Nontrivial Projection Problem asks whether every finite-dimensional normed space of dimension greater than one admits a well-bounded projection of non-trivial rank and corank or, equivalently, whether every centrally symmetric convex body (of arbitrary dimension greater than one) is approximately affinely equivalent to a direct product of two bodies of non-trivial dimension. We show that this is true "up to a logarithmic factor."
