Equivariant spectral triple for the quantum group $U_q(2)$ for complex deformation parameters

Satyajit Guin, Bipul Saurabh

Let $q=|q|e^{i\pi \theta },\theta \in (-1,1],$ be a nonzero complex number such that $|q|\ne 1$ and consider the compact quantum group $U_q(2)$. For $\theta \notin \mathbb{Q}\setminus \{0,1\}$, we obta…
