2:30 pm - 3:30 pm Julien Marché, IMJ, "Differential geometry on the character variety"
Abstract: We study the character variety of 3-manifolds groups into SL_2(C) and some natural structures on it like symplectic and volume forms.
We will relate these structures to the Kauffman module at order 1 with some applications to the asymptotics of quantum invariants.

4:00 pm - 5:00 pm Hongbin Sun, UC Berkeley, "Virtual domination of 3-manifolds"
Abstract: By constructing certain immersed $\pi_1$-injective 2-complexes in closed hyperbolic 3-manifolds, we show the following statement: For any closed oriented hyperbolic 3-manifold M, and any closed oriented 3-manifold N, M admits a finite cover M′ such that there exists a degree-2 map f : M′ → N, i.e. M virtually 2-dominates N.
