Relation between quantum invariants of 3-manifolds and 2-dimensional CW-complexes
Ivelina Bobtcheva, Frank Quinn
We show that the Reshetikhin-Turaev-Walker invariant of 3-manifolds can be normalized to obtain an invariant of 4-dimensional thickenings of 2-complexes. Moreover when the underlyi…

On Quinn's Invariants of 2-dimensional CW-complexes
Ivelina Bobtcheva
Given a semisimple stable autonomous tensor category over a field , to any group presentation with finite number of generators we associate an element invariant unde…
