This is an announcement for the paper "Saturating constructions for
normed spaces" by Stanislaw J. Szarek and Nicole Tomczak-Jaegermann  .


Abstract: We prove several results of the following type: given finite
dimensional normed space V there exists another space X with
log(dim X) = O(log(dim V)) and such that every subspace (or quotient) of X,
whose dimension is not "too small," contains a further subspace isometric
to V. This sheds new light on the structure of such large subspaces or
quotients (resp., large sections or projections of convex bodies) and
allows to solve several problems stated in the 1980s by V. Milman. The
proofs are probabilistic and depend on careful analysis of images of
convex sets under Gaussian linear maps.
