Michael Magee: Diophantine properties of Markoff-Hurwitz varieties

1:00pm, CM219

Beginning with the simple question
'when is the sum of the squares of a tuple of integers equal to a multiple of their product?',
one arrives at a family of Diophantine equations called Markoff-Hurwitz equations.
I will give a `high-level' accessible talk about these Diophantine equations with two broad themes:
Firstly, the Markoff-Hurwitz equations are important as a `critical' case in Diophantine geometry, and as such, have strange Diophantine properties.
Secondly, the Markoff-Hurwitz equations are intimately connected with a family of fractals that includes the `Rauzy gasket': a fractal that pops up in seemingly disparate areas of mathematics including triply periodic surfaces, dynamics of maps on the circle, higher dimensional generalizations of continued fractions, Teichmuller theory, and now, in Diophantine geometry.
This is partly based on joint work with Alex Gamburd and Ryan Ronan.

Delaram Kahrobaei: NP-Complete Problems in Graph Groups and Cryptographic Applications

1:00pm, E245

In this talk, we consider several classical and novel algorithmic problems for graph groups, which are also known as right-angled Artin groups or RAAGs. Many of these problems are closely related to graph theoretic problems, and their computational complexity is of intrinsic interest. Moreover, we are interested in these problems from the point of view of applications to cryptography. This is a joint work with R. Flores (Seville) and T. Koberda (Virginia).
