Abba Ramadan’s Colloquium
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: 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 StatesTitle: 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 StatesAWM and AMS are proud to present our next movie night on Thursday, April 6th at 5:30 pm in Gordon Palmer Hall 346.

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: 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

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: 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 StatesTitle: 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
