Abstract of a paper by Peter G. Casazza
This is an announcement for the paper "The simplified version of the Spielman and Sristave algorithm for proving the Bourgain-Tzafriri restricted invertiblity theorem" by Peter G. Casazza. Abstract: By giving up the best constants, we will see that the original argument of Spielman and Sristave for proving the Bourgain-Tzafriri Restricted Invertibility Theorem \cite{SS} still works - and is much simplier than the final version. We do not intend on publishing this since it is their argument with just a trivial modification, but we want to make it available to the mathematics community since several people have requested it already.
