Abstract
A generalization of Lozanovskii’s result is proved. Let E be k-dimensional sub-space of an n-dimensional Banach space with unconditional basis. Then there exist x 1,…, x k ⊂ E such that B E ⊂ absconv{x 1,…, x k } and
This answers a question of V. Milman which appeared during a GAFA seminar talk about the hyperplane problem. We add logarithmical estimates concerning the hyperplane conjecture for proportional subspaces and quotients of Banach spaces with unconditional basis.
