Character varieties of hyperbolic knot complements

To every hyperbolic 3-manifold M with nonempty boundary, one can associate a pair of related algebraic varieties X(M) and Y(M) called the character varieties of M. These varieties carry much topological info more››

The Steinberg symbol and special values of L-functions

In this talk, we will describe a construction of Eisenstein classes in the parabolic cohomology of Γ0(M) with values in Milnor's K2-group of the ring of S-integers of the cyclotomic extension Q( more››

Giving the physics a chance: how to reduce the impact of numerical errors

Numerical errors are generally a bother, but in the case of adverse mobility ratio flows, such as those encountered when injecting water or gas (CO2) in oil reservoirs, they can be a real nuisance. In this talk we discuss the well-known grid more››

Moving Unstructured Mesh Methods

Simulation of moving physical interfaces in 3-D is complicated by the need to (1) resolve complex realistic geometries with a spatial discretization, (2) accurately compute evolving physical fields on the discretization, and (3) evolve the di more››

An extension to the Brun-Titchmarsh theorem

The Siegel-Walfisz theorem states that for any B>0, we have Sp=x, p?d (mod v) 1 ~ x/f(v) log(x) for v = logB(x) and (v,d)=1. This only gives an asymptotic formula for the number of primes in an arithmetic progression for quite a small modulus v co more››

Manin conjectures for K3 surfaces

The Manin conjectures describe for geometrically easy varieties how the number of their rational points of bounded height should grow as the height bound varies. In this talk I will describe recent computations that suggest a similar statement for more››

Monitoring the health of Queensland's rivers: steps to designing an optimal spatial sampling scheme

Spatial sampling design is a key step in developing an optimal large-scale, multi-objective aquatic monitoring program. Aquatic systems can be complex and irregular, thus it is critical to ensure that a spatial design is statistically valid, imple more››

What is Mathematical Biology and How Useful is It?

Biological processes are very complex, and mathematical models of such processes are at best just a crude approximation. Nevertheless, one can gain some useful knowledge from the models. In this talk, I shall give examples of biological and biomed more››

Nonsmooth, Nonconvex Optimization

There are many algorithms for minimization when the objective function is differentiable or convex, but few options when it is neither. We describe two simple algorithmic approaches for minimization of nonsmooth, nonconvex objectives: BFGS (a new more››
