Applied Math Seminar – Yalchin Efendiev

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Speaker: Yalchin Efendiev (Department of Mathematics and Institute for Scientific Computation, Texas A&M University) Title:  Multicontinuum homogenization and applications Abstract: In this talk, I will talk about general approaches for multiscale modeling (closely related to porous media applications). I will mainly focus on numerical approaches, where multiscale finite element basis functions are constructed and used in

Abba Ramadan’s Colloquium

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Title: Stability of Nonlinear Waves in Hamiltonian PDE Abstract: Nonlinear dispersive wave equations arise as reduced mathematical models from governing equations of mathematical physics, such as the Navier-Stokes and Maxwell equations. These reduced models combine the leading-order balance between nonlinear and dispersive effects present in wave propagation. The existence and stability of coherent structures such

Uly Alvarez’s Colloquium

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Title: Cluster Algebras and Quiver Grassmannians Abstract: Since their conception, cluster algebras have made appearances in different fields such as algebra, combinatorics, geometry, and topology. For example, a class of objects from representation theory called quiver Grassmannians have been useful in describing the generators of cluster algebras using the Euler characteristic. This has motivated the

AWM and AMS Movie Night – Secrets of the Surface: The Mathematical Vision of Maryam Mirzakhani

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

AWM and AMS are proud to present our next movie night on Thursday, April 6th at 5:30 pm in Gordon Palmer Hall 346. Snacks will be provided! The movie is called "Secrets of the Surface: The Mathematical Vision of Maryam Mirzakhani" and it is about the life of Maryam Mirzakhani, the first woman to win

Applied Math Seminar – Teresa Portone, Sandia National Laboratories

Title: Quantifying model-form uncertainty with an application to subsurface transport Abstract: Computational models are increasingly used to make predictions affecting high-consequence engineering design and policy decisions. However, incomplete information about the represented phenomena and limitations in computational resources require approximations and simplifications that can lead to uncertainties in the computational models’ forms and errors in

Colloquium – Hailong Dao (University of Kansas)

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Title: Fractals and Syzygies Abstract: Syzygies are objects invented and utilized by David Hilbert in 1890 to study relations among polynomial equations, and have played a big role in the development of modern algebraic geometry. The quest to understand patterns of syzygies is both challenging and interesting, and sometimes reveals unexpected connections to other branches

Applied Math Seminar – Ali Pakniyat (Department of Mechanical Engineering, The University of Alabama)

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Title: Dualities in optimal control theory Abstract: Duality is a mathematical principle which, when it emerges, signifies the intrinsic relations between two distinct concepts, theorems or structures. In this talk, I will present three dualities which emerge in optimal control theory: (i) the duality in the Minimum Principle (MP) between the finite dimensional spaces of state variations
