Uniformity and isotypic smallness for quantum-group representations

Compact-group representations on Banach spaces are known to be norm-continuous precisely when they have finite spectra.

For a quantum group with continuous-function algebra $\mathcal{C}(\mathbb{G})$ norm continuity can be cast analogously as the bounded weak$^*$-norm continuity of the representation's attached maps $\mathcal{C}(\mathbb{G})^*\to \mathrm{End}(E)$ and its mirror counterpart $E_{\le 1}\times E^*_{\le 1}\to \mathcal{C}(\mathbb{G})$.

While the uniformity/isotypic finiteness equivalence no longer holds generally, it does (for the latter map) for compact quantum groups either coamenable or having dimension-bounded irreducible representations.

This generalizes the aforementioned classical variant, providing two independent quantum-specific mechanisms of recovering it.
