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: Critical Perturbations and Solvability for Elliptic Equations Abstract: In this talk we will present recent results concerning solvability of certain Boundary Value Problems associated to a general linear second order elliptic equation, under the assumption that the equation is close, in some critical Lebesgue spaces for the coefficients, to an equation for which solvability

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
Alabama Insurance Society Holds Actuarial Science Info Session
ZoomThis week Tuesday, September 22, the Actuarial Section of AIS will host its first meeting of the year at 7:00pm via Zoom. This meeting will be an informal opportunity for all students of any major or minor to learn what an actuary is, where actuaries work, how actuaries become credentialed, and how UA’s curriculum can
Analysis Seminar – Bruno Poggi (University of Minnesota)
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

Algebra/Topology Seminar – Honghao Gao (Michigan State University)
ZoomTitle: Legendrian invariants, Lagrangian fillings and cluster algebras Abstract: Classifications of Legendrian knots and their exact Lagrangian fillings are central questions in low-dimensional contact and symplectic topology. Recent development suggests that one can use cluster seeds to distinguish exact Lagrangian fillings. It requires a filling-to-cluster functoriality over a moduli space of Legendrian invariants. This invariant

ZoomTitle: On a structure theorem of doubling weights, Muckenhoupt Ap weights and reverse Holder weights. Abstract: In this talk, I will introduce a way to construct an explicit family of measures on the real line that are p-adic doubling for any finite set of primes, however, not doubling. This part generalizes the work of Boylan,
