The von Neumann algebraic quantum group ${\mathrm{SU}}_q(1,1)⋊{\mathbb{Z}}_2$ and the DSSYK model

Koen Schouten, Mikhail Isachenkov

The double-scaling limit of the SYK (DSSYK) model is known to possess an underlying ${\mathcal{U}}_q(\mathfrak{su}(1,1))$ quantum group symmetry. In this paper, we provide, for the f…
