Local Statistics of the Laplace Spectrum on 3D Rectangular Flat Tori
Wooyeon Kim
4:30pm|314 Fine Hall

In this talk, we show that the pair correlation of the Laplacian eigenvalues on 3-dimensional rectangular flat tori follows Poissonian statistics. Similar to the earlier work of Eskin, Margulis, and Mozes on 2D flat tori, these eigenvalues are...

The Wiegold Problem and the Normal Rank of Free Products
Lvzhou Chen
4:30pm|314 Fine Hall

The normal rank (or weight) of a group G is the smallest number of elements that normally generate G. This plays an important role in 3-manifold topology, but it is poorly understood. It is extremely difficult to give lower bounds apart from looking...

Arithmetic on Markoff Surfaces
Daniel Martin
4:30pm|Simonyi 101

The generalized Markoff equation gives rise to a dynamical system via the Markoff group acting on the solution set. This talk considers the resulting dynamics over finite fields, which has strong connections with combinatorial group theory and...
