Abstract:
We construct an example of a Hilbert $C^*$-module which shows that Troitsky's theorem on the
geometric essence of $\mathcal{A}$-compact operators between Hilbert $C^*$-modules
cannot be extended to modules which are not countably generated
case (even in the case of a stronger uniform structure, which is also introduced).
In addition, the constructed module admits no frames.
Keywords:
Hilbert $C^*$-module, uniform structure, totally bounded set, compact operator, $\mathcal{A}$-compact operator, locally compact space, Radon measure.
