AWI Presents: Water H.U.B. Talks series; An opportunity for researchers to come together.
Bevill Building, Room 1000 201 7th Avenue, Tuscaloosa, AL, United StatesTitle: Hydrodynamic Driven Dissolution In Carbonate Formations: Application to Sinkhole Formation Investigation The extremes of rainfall, extended drought seasons, and groundwater overuse accelerate the formation of sinkholes. In the United States, 20% of the land surface is karst and susceptible to sinkhole formation, especially in Texas, Alabama, Missouri, Kentucky, Tennessee, Pennsylvania, and Florida. Despite the increased

ZoomTitle: Regular Lip(1,1/2) Approximation of Parabolic Hypersurfaces Abstract: A classical result of David and Jerison states that a regular, n-dimensional set in R^{n+1} satisfying a two sided corkscrew condition is quantitatively approximated by Lipschitz graphs. After reviewing this result, we will discuss some recent advances in extending this result to the parabolic setting. The proofs

ZoomTitle. Additive and scalar-multiplicative Carleson perturbations of elliptic operators on domains with low dimensional boundaries. Abstract. At the beginning of the 90s, Fefferman, Kenig and Pipher (FKP) obtained a rather sharp (additive) perturbation result for the Dirichlet problem of divergence form elliptic operators. Without delving into details, the point is that if the (additive)
Colloquium – John Baldwin (Boston College)
ZoomTitle: Floer homology and the fundamental group Abstract: The most important invariant of a 3-manifold is its fundamental group. One of the most fruitful approaches to understanding the fundamental group is to study its homomorphisms into simpler groups. SU(2) is an especially convenient choice of target because it is one of the simplest non-abelian Lie
AWM Lunch and Learn
Our first ever virtual Lunch and Learn will be on Wednesday, September 30, 2020 at 12:00 p.m. via zoom. We will be talking about Mathematics and Modeling COVID19. Please email awm@ua.edu for the Zoom link and password.
Applied Math Seminar – Amanda Koh (UA Dept. of Chemical and Biological Engineering)
ZoomTITLE: Deformable inclusion jamming for improved magnetorheological performance Abstract: Magnetorheological fluids (MRFs) are simple systems of magnetic particles dispersed in a non-magnetic carrier fluid. When a magnetic field is applied to the MRF, magnetic particles form chains and the fluid becomes more solid-like and able to resist shear forces. This liquid to solid transition, which

ZoomTitle: Regularization methods for the Poisson-Boltzmann model with sharp or diffuse interfaces Abstract: Both the sharp interface and diffuse interface Poisson-Boltzmann (PB) models have been presented in the literature for studying electrostatic interactions between a solute molecule and its surrounding solvent environment. In the mathematical analysis and numerical computation for these PB models, a significant
Algebra/Topology Seminar – Yi Ni (California Institute of Technology)
ZoomTitle: The second term in knot Floer homology Abstract: It is well known that the genus g of a knot is the highest Alexander grading for which the knot Floer homology is nontrivial. In recent years, there is evidence suggesting that the knot Floer homology is also nontrivial in the Alexander grading g-1. In this talk, I

ZoomTITLE: Revealing the mechanisms of molecular motors’ motility by using computational approaches ABSTRACT: Dynein is a molecular motor for cargo transportation and force generation in cells. Dysfunction of dynein is associated with many diseases, such as ciliopathies, lissencephaly and other neurodegeneration disorders. Understanding the functions of dynein is crucial for developing new treatments of such

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Matrix weights, the convex-set valued maximal operator, and Rubio de Francia extrapolation Abstract: In this series of talks (I project three), I want to talk about the theory of matrix weights: its history and motivation, and some recent results by myself, Kabe Moen, and others. The ultimate goal is to give an overview of
