Session 4. Banach Spaces and Operator Theory with Applications

Rademacher boundness versus gaussian-boundness

Stanisław Kwapień, Warsaw University, 
The talk is based on the joint work with Mark Veraar (Delft Univeristy) and Lutz Weis (Karlsruhe Univerisity)
We prove that given Banach spaces \(X\) the concepts of Rademacher boundness and gaussian-boundness for families of operators from \(X\) coincide if and only if \(X\) has a finite cotype. Simialar properties are proved for related concepts in the case of Banach lattices \(X\).
