Unlike incompressible single-fluid flows, the velocity
Analysis Seminar – David Cruz-Uribe (UA)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Everything I knew (and maybe that you know) about the Stieltjes integral is wrong. Abstract: I will discuss three definitions of the Riemann integral (the Riemann integral, the Darboux integral, and a variant of the Darboux integral) and why they are equivalent. I will then introduce the generalizations of these results to define the

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTITLE: A Descent Scheme for Thick Elastic Curves with Self-contact and Container Constraints Abstract: We present a numerical method to simulate thick elastic curves that accounts for self-contact and container (obstacle) constraints under large deformations (the motivating model is DNA packing). The base model includes bending and torsion effects, as well as inextensibility. A minimizing movements, descent

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Geometry of algebraic surfaces via combinatorics of cones Abstract: Effective, nef, semiample cones of projective manifolds are fundamental tools in algebraic geometry. They tell us about the geometry of projective manifolds and there are lots of studies about them. However, we still do not know much about these invariants of projective manifolds of general

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Geometry of algebraic surfaces via their Cox rings Abstract: Cox ring is an important tool in modern algebraic geometry and several other branches of mathematics. In the first part of this talk, I will briefly review basic theory of Cox ring and explain how it connects birational geometry and geometric invariant theory. Then I

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTITLE: A Discussion of Variational Models for Phase Transitions Abstract: Variational models are an important way of describing many different phenomena. In this talk, we'll first provide motivation for a variational model for phase transitions and discuss some of its properties. We will then describe how this phase model relates to other variational models.
