Calkin representations for $L^{p}$

Functional Analysis 2019-09-23 v2

Abstract

We identify the weak closures of the ranges of certain Calkin representations for LpL^{p}, 1<p<1<p<\infty. As a consequence, assuming the continuum hypothesis, we show that the commutant of B(Lp)B(L^{p}), 1<p<1<p<\infty, in its ultrapower may or may not be trivial depending on the ultrafilter. This extends a result of Farah, Phillips and Stepr\=ans.
