A Hilbert C*-module with extremal properties

arXiv:2107.03782 · doi:10.1134/S0016266322010075

Abstract

We construct an example of a Hilbert C*-module which shows that Troitsky's theorem on the geometrical essence of A-compact operators between Hilbert C*-modules is not extendable to a not countably generated module case (even in the case of a stronger uniform structure, which is also introduced). In addition, the constructed module admits no frames.
