Five Hilbert Space Problems in Operator Algebras

Marcoux, Laurent (Springer, 2022-11-03)

A number of questions which have been solved over the years in the theory of single operators acting on Hilbert space have interesting analogues when recast in the setting of elements of C*-algebras. We list five of these, ...
On *-similarity in C*-algebras

Marcoux, Laurent; Radjavi, Heydar; Yahaghi, B.R. (Instytut Matematyczny, 2020)

Two subsets X and Y of a unital C -algebra A are said to be -similar via s 2 A􀀀1 if Y = s􀀀1Xs and Y = s􀀀1X s. We show that this relation imposes a certain structure on the sets X and Y, and that under certain natural ...
