Schubert polynomials concretely embody the remarkable connection between the geometry of the flag variety G L ( n ) / B and the combinatorics of the symmetric group. This talk will develop similar story for the forest polynomials recently introduced...

In this talk, we study a variational problem that provides a way to extend minimizing geodesics connecting two given probability measures in the Wasserstein space for all times. This is achieved by allowing negative coefficients in the classical...

Shape analysis is a framework for treating complex data and obtain metrics on spaces of data. Examples are spaces of unparametrized curves, time-signals, surfaces and images. In this talk we discuss structure preservation and deep learning for...

Life is a nonequilibrium phenomenon where nonlocal processes play a prominent and increasingly important role. Nonlocal models have emerged as a robust mathematical framework for capturing interactions across spatial and temporal scales in the life...

Sharon and Joerg are members of the Boeing Applied Mathematics organization. They partner with business units to develop applied math solutions and tools that help Boeing reduce costs, improve products and operations. In this presentation, Sharon and...

In an electric grid, 'phase imbalance' refers to the unequal distribution of electrical loads across the three phases of the grid. This imbalance can lead to inefficiencies, increased power losses, and equipment damage. A helpful analogy is a three...

The van Eeden seminar is a yearly event in which graduate students vote for their favorite statisticians. The winner is contacted by the organizing committee and invited to give a talk in the department’s seminar. The speaker spends one or two days...

Distances between the roots of a fixed polynomial appear organically in many places in number theory. For any $f(x) \in \mathbb{Z}[x]$, let $\operatorname{sep}(f)$ denote the minimum distance between distinct roots of $f(x)$. Mahler initiated the...

Given a matching M of a hypercube, does there exist a Hamiltonian cycle that contains every edge of M? This problem was posed by Ruskey and Savage in 1993, and remains open. If M is a perfect matching a Hamiltonian cycle does exist, as shown by Fink...

Locally gentle algebras are a class of infinite-dimensional, non-connected algebras which have nice combinatorial interpretation in terms of quivers with relations. These relations ensure that each arrow is contained in a unique maximal path. In this...
