Polylog dimensional subspaces of

Gideon Schechtman, Nicole Tomczak--Jaegermann

We show that a subspace of of of dimension contains -isomorphic copies of where tends to infinity with $n/(\log N\l…

On the geometry of projective tensor products

Ohad Giladi, Joscha Prochno, Carsten Schütt +2

In this work, we study the volume ratio of the projective tensor products with . We obtain asymptotic…

On approximations by projections of polytopes with few facets

Alexander E. Litvak, Mark Rudelson, Nicole Tomczak-Jaegermann

We provide an affirmative answer to a problem posed by Barvinok and Veomett, showing that in general an n-dimensional convex body cannot be approximated by a projection of a sectio…

On the nontrivial projection problem

Stanislaw J. Szarek, Nicole Tomczak-Jaegermann

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 o…

Majorizing measures and proportional subsets of bounded orthonormal systems

Olivier Guedon, Shahar Mendelson, Alain Pajor +1

In this article we prove that for any orthonormal system $(\vphi_j)_{j=1}^n \subset L_2$ that is bounded in , and any , there exists a subset of cardinali…

On norm closed ideals in L(\ell_p\oplus\ell_q)

B. Sari, Th. Schlumprecht, N. Tomczak-Jaegermann +1

It is well known that the only proper non-trivial norm-closed ideal in the algebra L(X) for X=\ell_p (1 \le p < \infty) or X=c_0 is the ideal of compact operators. The next natural…
