Eric Geiger, NC State, Non-congruent non-degenerate curves with identical signatures

October 28 | 2:00 pm - 3:00 pm EDT
Zoom,

This talk will focus on using the Euclidean Signature to determine whether two smooth planar curves are congruent under the Special Euclidean group. Work done by Emilio Musso and Lorenzo Nicolodi emphasizes that signatures must be used with caution by constructing 1-parameter families of…

Braxton Osting, University of Utah, Consistency of archetypal analysis

October 28 | 3:00 pm - 4:00 pm EDT
Zoom,

Archetypal analysis is an unsupervised learning method that uses a convex polytope to summarize multivariate data. For fixed k, the method finds a convex polytope with k vertices, called archetype points, such that the polytope is contained in the convex…

Noemi Petra, UC Merced, Inferring the basal sliding coefficient field for the Stokes ice sheet model under rheological uncertainty

November 3 | 3:00 pm - 4:00 pm EST
Zoom,

We consider the problem of inferring the basal sliding coefficient field for an uncertain Stokes ice sheet forward model from surface velocity measurements. The uncertainty in the forward model stems from unknown (or uncertain) auxiliary parameters (e.g., rheology parameters). This inverse problem is posed within…

Nick Barron, University of Loyola, Applications of Quasiconvex functions to HJ Equations and Optimal Control

November 4 | 3:00 pm - 4:00 pm EST
Zoom,

Quasiconvex functions, a major generalization of convex functions, naturally arise in calculus of variations, optimal control and differential games in L-infinity. This connection with HJ equations, representation formulas, obstacle problems, and reach-avoid problems will be discussed. Zoom meeting ID: 802…
