Noncommutative Lp modules

Research output: Contribution to journalArticlepeer-review


We construct classes of von Neumann algebra modules by considering "column sums" of noncommutative V spaces. Our abstract characterization is based on an Lp/2-valued inner product, thereby generalizing Hilbert C*-module's and representations on Hilbert space. While the (single) representation theory is similar to the L2 case, the concept of Lp bimodule (p ≠ 2) turns out to be nearly trivial.
