[Banach] Abstract of a paper by S.V. Astashkin, D.V. Zanin, E.M. Semenov, F.A. Sukochev

This is an announcement for the paper "Kruglov operator and operators defined by random permutations" by S.V. Astashkin, D.V. Zanin, E.M. Semenov, and F.A. Sukochev.

Abstract: The Kruglov property and the Kruglov operator play an important role in the study of geometric properties of r.i. function spaces. We prove that the boundedness of the Kruglov operator in a r.i. space is equivalent to the uniform boundedness on this space of a sequence of operators defined by random permutations. It is shown also that there is no minimal r.i. space with the Kruglov property.
