Differential Equations and Nonlinear Analysis Seminar: Jameson Graber, Baylor University, The Master Equation in Mean Field Game Theory
ZoomMean field game theory was developed to analyze Nash games with large numbers of players in the continuum limit. The master equation, which can be seen as the limit of an…
Stochastics Seminar: Grigory Terlov, UNC-Chapel Hill, Random optimization problems at fixed temperatures
SAS 4201We consider a class of disordered mean-field combinatorial optimization problems, focusing on the Gibbs measure, where the inverse temperature does not vary with the size of the graph and the…
Applied Math Graduate Student Seminar: Julia Sanger, NC State, Modeling interactions between platelet-like particles and fibrin matrix for wound healing applications
SAS 4201In wound healing applications, platelet-like particles (PLPs) are engineered biomaterials that aim to mimic the behavior of natural platelets. Platelets play an essential role in the successful formation of the…

Geometry and Topology Seminar: Tye Lidman, NC State, Cosmetic surgeries and gauge theory
SAS 4201The famous knot complement theorem of Gordon and Luecke states that two knots in the three-sphere are equivalent if and only if the complements are homeomorphic. This was proved more…

SAS 4104Differential Equations and Nonlinear Analysis Seminar: Olivier Glass, Université Paris-Dauphine, Small solids in Euler flows
SAS 4201In this talk, I will discuss the evolution of rigid bodies in a perfect incompressible fluid, and the limit systems that can be obtained as the bodies shrink to points. The…
Computational and Applied Mathematics Seminar: Saviz Mowlavi, MERL, Model-based and data-driven prediction and control of spatio-temporal systems
ZoomSpatio-temporal dynamical systems, such as fluid flows or vibrating structures, are prevalent across various applications, from enhancing user comfort and reducing noise in HVAC systems to improving cooling efficiency in…
Stochastics Seminar: Nick Cook, Duke, Branching Brownian motion and the Road-Field Model
SAS 4201The Fisher-KPP equation was introduced in 1937 to model the spread of an advantageous gene through a spatially distributed population. Remarkably precise information on the traveling front has been obtained…
Applied Math Graduate Student Seminar: Walker Powell, Sensitivity Analysis of Attracting Dynamical Systems via Optimal Transport of Invariant Measures
SAS 4201Determining the sensitivity of model outputs to input parameters is an important precursor to developing informative parameter studies, building surrogate models, and performing rigorous uncertainty quantification. A prominent class of…
Colloquium: Nikolaos Kapouleas, Brown University, Minimal Surface Doublings and Their Geometry
SAS 4201Minimal surfaces are fundamental geometric objects which have been studied intensively since the 1700's. Classes of minimal surfaces of particular interest are the complete embedded ones in Euclidean space, closed…
Symbolic Computation Seminar: Sriram Gopalakrishnan, Sorbonne Université, The arithmetic complexity of computing Grobner bases of determinantal systems
SAS 4201Determinantal systems are systems of polynomial equations which encode a rank deficiency of a given matrix with polynomial entries over the solution set to other polynomial equations. Such systems arise…
Geometry and Topology Seminar: Irina Kogan, NC State, An Introduction to Computational Invariant Theory (Part I)
SAS 4201Invariants withstand transformations and, therefore, represent the essence of objects or phenomena. In mathematics, transformations often constitute a group action. Since the 19th century, studying the structure of various types…
Algebra and Combinatorics Seminar: Greg Muller, University of Oklahoma, Friezes of Dynkin type
SAS 4201A "frieze" is an infinite strip of numbers satisfying certain determinantal identities, or any one of several generalizations of this idea. In this talk, I will give an introduction to…

Differential Equations and Nonlinear Analysis Seminar: Aris Daniilidis, TU Wien, Slope determination: from convex to Lipschitz continuous functions
ZoomA convex continuous function can be determined, up to a constant, by its remoteness (distance of the subdifferential to zero). Based on this result, we discuss possible extensions in three…
Computational and Applied Mathematics Seminar: Jian-Guo Liu, Duke University, Optimal Control for Transition Path Problems in Markov Jump Processes
