Graded spherical skein 2+1-G-HQFT and modified Turaev-Viro invariants

Francesco Costantino, Nathan Geer, Benjamin Haïoun +1

For G a group, we present a G-graded version of chromatic maps and skein modules and use them to define a 2+1-G-HQFT out of a G-chromatic category. The construction applies to the…

Quantum invariants arising from $U_{h} sl (2∣1)$ are q-holonomic

Jennifer Brown, Nathan Geer

We show that the quantum invariants arising from typical representations of the quantum group $U_{h} sl (2∣1)$ are q-holonomic. In particular, this implies the existence of…
