A remark on the slicing problem
Apostolos Giannopoulos, Grigoris Paouris, Beatrice-Helen Vritsiou
The purpose of this article is to describe a reduction of the slicing problem to the study of the parameter I_1(K,Z_q^o(K))=\int_K ||< :, x> ||_{L_q(K)}dx. We show that an upper bo…
On the approximation of a polytope by its dual -centroid bodies
Grigoris Paouris, Elisabeth M. Werner
We show that the rate of convergence on the approximation of volumes of a convex symmetric polytope P in R^n by its dual L_{p$-centroid bodies is independent of the geometry of P.…
Isomorphic properties of Intersection bodies
A. Koldobsky, G. Paouris, M. Zymonopoulou
We study isomorphic properties of two generalizations of intersection bodies, the class of k-intersection bodies and the class of generalized k-intersection bodies. We also show th…
A note on subgaussian estimates for linear functionals on convex bodies
Apostolos Giannopoulos, Alain Pajor, Grigoris Paouris
We give an alternative proof of a recent result of Klartag on the existence of almost subgaussian linear functionals on convex bodies. If is a convex body in wi…
