Research output: Contribution to journalArticlepeer-review


We provide a (2+1)-dimensional TQFT model for the colored Turaev-Viro invariants, considering a relative version of these invariants. We then describe the linear maps corresponding to cobordisms of tori with an embedded colored θ-curve. This enables us to give a formula for torus knots in a lens space.
