Lars Ruthotto, Emory University, Numerical Analysis Perspectives on Deep Neural Networks
ZoomThe resurging interest in deep learning is commonly attributed to advances in hardware and growing data sizes and less so to new algorithmic improvements. However, cutting-edge numerical methods are needed…
Differential Equations and Nonlinear Analysis Seminar: Roberto Cominetti, Universidad Adolfo Ibáñez, Chile, Convergence rates for Krasnoselskii-Mann fixed-point iterations
ZoomA popular method to approximate a fixed point of a non-expansive map is C is the Krasnoselskii-Mann iteration. This covers a wide range of iterative methods in convex minimization, equilibria,…
Prerona Dutta, NC State, Metric entropy and nonlinear partial differential equations
ZoomChair: Tien Khai Nguyen, contact for Zoom access.
Vakhtang Putkaradze, Variational Methods for Active Porous Media
ZoomMany biological organisms are comprised of deformable porous media, with additional complexity of an embedded muscle. Using geometric variational methods, we derive the equations of motion for the dynamics of…
Dylan Bates, NC State, Virtual reinforcement learning for balancing an inverted pendulum in real time
ZoomChair: Hien Tran (tran@ncsu.edu, contact for Zoom access)
Peter Pivovarov, University of Missouri, Stochastic functional inequalities and shadow systems
ZoomI will discuss stochastic geometry of random concave functions. In particular, I will explain how a "local" stochastic dominance underlies several functional inequalities. Emphasis will be on a notion of…
Julia Plavnik, Indiana University, On odd-dimensional modular tensor categories
ZoomModular tensor categories arise naturally in many areas of mathematics, such as conformal field theory, quantum groups and Hopf algebras, low dimensional topology, representations of braid groups, and they have…
Paul Cazeaux, The University of Kansas, Twisted, incommensurate layered materials: modeling, computations and topology
ZoomTwo-dimensional crystals have been intensely investigated both experimentally and theoretically since graphene was exfoliated from graphite. Physicists have recently developed the ability to stack one layer on another with a…
Differential Equations and Nonlinear Analysis Seminar: Tyrus Berry, George Mason University, A Manifold Learning Approach to Boundary Value Problems
ZoomMesh-free methods for boundary value problems (BVPs) can be convenient on manifolds where generating a mesh may be difficult or when the manifold is not known explicitly but is determined…
Woden Kusner, University of Georgia, Measuring chirality with the wind
ZoomThe question of measuring "handedness" is of some significance in both mathematics and in the real world. Propellors and screws, proteins and DNA, in fact *almost everything* is chiral. Can…
Stanislaw Szarek, Case Western Reserve University/Sorbonne Université
ZoomZoom ID: 936 5420 1948 Password: the last four digits of the Zoom ID in reverse order
Hussam Al Daas, STFC, Rutherford Appleton Laboratory, Two-level Nyström—Schur preconditioner for symmetric positive definite matrices
ZoomRandomized methods are becoming increasingly popular in numerical linear algebra. However, few attempts have been made to use them in developing preconditioners. Our interest lies in solving large-scale sparse symmetric…
Differential Equations and Nonlinear Analysis Seminar: Alessio Porretta, Università di Roma Tor Vergata, Long time behavior in mean field game systems
ZoomMean field game PDE systems were introduced by J-M. Lasry and P.-L. Lions to describe Nash equilibria in multi-agents dynamic optimization. In the simplest model, those are forward-backward systems coupling…
Dustin Kapraun, EPA, SIAM Mathematics in Industry Series
ZoomDustin Kapraun attained degrees in mathematics (B.S., 1998), physics (M.S., 2002), and applied mathematics (Ph.D., 2014), all from North Carolina State University. After finishing the Ph.D., he completed two postdoctoral…
Vishesh Jain, Stanford University, On the real Davies’ conjecture
ZoomWe show that every $n \times n$ real matrix $A$ is within distance $\delta \|A\|$ in the operator norm of an $n\times n$ real matrix $A'$ whose eigenvectors have condition…
