Graduate Student Seminar

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.

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.
