Workshop on Geometric Structures on 3-manifolds

Virtual domination of 3-manifolds
Hongbin Sun
4:00pm|Simonyi Hall 101
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...

Workshop on Geometric Structures on 3-manifolds

Differential geometry on the character variety
Julien Marché
2:30pm|Simonyi Hall 101

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...

Invariants of random knots
Chaim Even Zohar
10:30am|West Bldg. Lect. Hall

A knot is a closed curve embedded in the three-dimensional space, like a rope whose two ends are joined together. As usual in Topology, two knots are equivalent if one can be deformed into the other by continuous moves, where stretching and...

Computer Science/Discrete Mathematics Seminar I

Is optimization computationally equivalent to online learning?
Elad Hazan
11:15am|West Bldg. Lect. Hall

Vapnik's fundamental theorem of statistical learning establishes a computational equivalence between optimization (empirical risk minimization) and learning in the statistical setting. Is the same true for learning in games? We give a precise answer...
