Analysis Seminar – David Cruz-Uribe, University of Alabama
Title: A gentle introduction to Rubio de Francia extrapolation Abstract
Applied Math Seminar – Brendan Ames, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Semidefinite relaxation of the clustering problem and first-order methods for their solution Abstract: I will discuss a novel relaxation approach for the graph clustering problem. Although intractable in worst-case, much recent research has established that clusters can be recovered if the underlying network or data is well-behaved. In particular, I will provide conditions on
Applied Math Seminar – Wei Zhu, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: New augmented Lagrangian method for a curvature dependent segmentation model Abstract: Augmented Lagrangian methods (ALMs) have proved to be successful for the minimization of curvature dependent functionals in image processing. However, those ALM based algorithms often suffer from choosing appropriate penalty parameters in the numerical implementation. In this talk, we will discuss our recent
Analysis Seminar – Kabe Moen, University of Alabama
227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Commutators and weighted norm inequalities Abstract: We will review the theory of commutators and BMO functions. As an application of the theory of weighted norm inequalities we will show that the commutator of an operator that satisfies certain weighted norm inequalities is bounded on L^p. We also show show a converse to this result.
Colloquium – Zhimin Zhang, Wayne State University
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTopic: Polynomial Preserving Recovery for Gradient and Hessian Abstract: Post-processing techniques are important in scientific and engineering computation. One of such technique, Superconvergent Patch Recovery (SPR) proposed by Zienkiewicz-Zhu in 1992, has been widely used in finite element commercial software packages such as Abaqus, ANSYS, Diffpack, etc.; another one, Polynomial Preserving Recovery (PPR) has been

Colloquium – Ricardo Cortez, Tulane University
302 Gordon Palmer HallMathematical and Computational Modeling of Microorganism Swimming Motions Microscopic swimmers like bacteria and spermatozoa live in highly viscous environments. Their locomotion and the fluid flows they generate around them have been actively investigated for the last 60 years motivated by questions about effective locomotion strategies, the organism's interaction with the surrounding environment, patterns of collective

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Time reversal acoustic communication in the ocean Abstract: The global marine ecosystem is undergoing significant changes due to human activities and natural processes. These changes call for enhanced capabilities to sample and communicate in the oceans. With this background, underwater acoustic communication has attracted much attention across multiple disciplines, as this key subsea technology
