On the density and surjectivity of -Witten-Reshetikhin-Turaev quantum representations

Renaud Detcherry, Pierre Godfard, Ramanujan Santharoubane

In this paper, we establish several new fundamental properties of -quantum representations $ρ_{p,g,\underlineλ}\colon\mathrm{PMod} (Σ_{g,n})\longrightarrow \math…

Rigidity of and quantum representations of mapping class groups at prime levels

Pierre Godfard

We prove the rigidity of Witten-Reshetikhin-Turaev and quantum representations of mapping class groups at all prime levels for closed surfaces of…

Conformal blocks are quasi-geometric

Pierre Godfard

We prove that the bundles with flat connections on configuration spaces associated to braided fusion categories, as well as the bundles with flat connections on moduli spaces of cu…

Hodge structures on conformal blocks

Pierre Godfard

We prove existence and uniqueness of complex Hodge structures on modular functors. The proof is based on the non-Abelian Hodge correspondence and Ocneanu rigidity. Given a modular…

Semisimplicity of conformal blocks

Pierre Godfard

We prove that braid group representations associated to braided fusion categories and mapping class group representations associated to modular fusion categories are always semisim…

Rigidity of Fibonacci representations of mapping class groups

Pierre Godfard

We prove that level Witten-Reshetikhin-Turaev quantum representations, also known as the Fibonacci representations, of mapping class groups are locally rigid.…
