VIGRE Graduate Student Seminar
2:00pm, Room 302
Speaker: Bree Ettinger, University of Georgia
Title of talk: Surrogate Models for a Simple Oil Reservoir
Abstract: This VIGRE talk will be summary the Exxon Mobile Teams findings from the IMA Math Modeling Workshop, in which we examined different algorithms to build surrogate models for a simple oil reservoir. Besides estimating NPV for certain high/low scenarios, we used surrogate models to find optimal producer well locations and to perform simple history matching of a 2D permeability field.

Arithmetic Geometry/Number Theory
3:30pm, Room 304
Speaker: Jerry Hower, University of Georgia
Title of talk: Ruling out elliptic curves of prime conductor.
Abstract: We will prove the non-existence of elliptic curves of certain prime conductors over certain quadratic number fields by using properties about ramification in its division fields.

Title of talk: Finite Type Invariants for Vectorfields
Abstract: In this talk, we discuss the possibility of constructing general finite type invariants for vectorfields on domains in R^3. We are interested in "invariant integrals" of flows which are preserved under diffeomorphisms of the domain and field. The first such invariant is the helicity of a field, which is a kind of linking number. We present a new (?) approach to defining helicity and proving that it is diffeomorphism invariant, inspired by the formal structure of Bott-Taubes integration. This formulation naturally suggests an approach to constructing new vector field invariants. This talk is joint work with Jason Parsley.
