[Banach] Abstract of a paper by Richard Lechner

This is an announcement for the paper "The one-third-trick and shift operators" by Richard Lechner.

Abstract: In this paper we obtain a representation as martingale transform operators for the rearrangement and shift operators introduced by T. Figiel. The martingale transforms and the underlying sigma algebras are obtained explicitly by combinatorial means. The known norm estimates for those operators are a direct consequence of our representation.
