Frames in Hilbert $C^*$-modules

School
MATHEMATICS

Whether every Hilbert $C^*$-module over a $C^*$-algebra $A$ admits a frame, is an interesting open question in Hilbert $C^*$-module theory. In general, the response to this question is negative and every Hilbert $C^*$-module over a commutative $C^*$-algebra $A$ admits a frame if and only if $A$ is a finite dimensional $C^*$-algebra. Indeed, the conjecture is that every Hilbert $C^*$-module over a $C^*$-algebra $A$ admits a frame, if and only if $A$ is a $C^*$-algebra of compact operators. The main purpose of this talk is to give a partially affirmative response to this conjecture, by considering the Elliott-Kawamura categorical approach to ...
