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
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

Title: Heat extensions of doubling weights and A_infty A_infty weights play a fundamental role in weighted inequalities for operators used in harmonic analysis. It is known that if w is an A_infty weight then log w in the space of bounded mean oscillation (BMO) and the converse is `almost’ true (up to taking a

Unlike incompressible single-fluid flows, the velocity

302 Gordon Palmer HallTitle: Standing Waves of the Schrodinger Equation with Concentrated Nonlinearity With Atanas Stefanov, we study the concentrated Nonlinear Schrodinger Equations in n-dimensions, with power non-linearities, driven by the fractional Laplacian. We construct the solitary waves explicitly, in an optimal range of the parameters, so that they belong to the natural energy space $H^s$. We

The degenerate Cahn-Hilliard equation is a widely used model for

302 Gordon Palmer HallTitle: Mixed Weak-Type Estimates for Classical Operators Abstract: We prove new mixed weak type estimates for various classical operators of Harmonic analysis. Mixed weak type inequalities were first studied by Muckenhoupt and Wheeden and later by Sawyer to prove the $L^p$ boundedness of the Hardy-Littlewood maximal operator as a consequence of the Jones factorization
