Very discrete groups
Sam Corson (University of the Basque Country)
3:30 PM in 427 SEO
Some groups are so discrete that abstract homomorphisms from many of the standard continuous topological groups to such a group always have open kernel. It was known classically that any homomorphism from a completely metrizable group to a free group has open kernel. I'll talk about the history of such results and give a plethora of new examples. Joint work with Greg Conner.

Interaction of modulated water waves of finite depth
Yannis Giannoulis (University of Ioannina, Greece)
4:00 PM in 636 SEO
In this talk we consider the water wave problem of finite depth as a nonlinear dispersive system. Motivated by this feature, we are interested in the macroscopic dynamics of the envelopes of small, macroscopically amplitude-modulated fixed carrier waves, the latter being plane wave solutions of the linearized problem. More specifically, we want to know whether some sort of interaction of different (modulated) carrier waves can be observed macroscopically. For pure gravity waves such a macroscopic interaction can be observed only for the next-to-leading order corrections of the macroscopic amplitudes and a relevant system of modulation equations is derived. This system is then justified by employing the stability of the original water wave problem, as established by Lannes in his 2013 book. Time permitting, we discuss also the completely different situation in the case of capillary-gravity water waves, where for resonant carrier waves macroscopic interactions can be observed for the leading order amplitudes and where a stability result for the original water wave problem has to take into account the second-order differential operator of the surface tension.

Sufficient dimension folding via distance covariance
Wenhui Sheng (Marquette University)
4:00 PM in 636 SEO
We propose a new sufficient dimension folding method using distance covariance for regression in which the predictors are matrix- or array-valued. The method works efficiently without strict assumptions on the predictor. It is model-free and neither smoothing techniques or selection of tuning parameters is needed. Moreover, it works for both univariate and multivariate response cases. We use two approaches to estimate the structural dimensions: bootstrap method and a new method of local search. Simulations and real data analysis support the efficiency and effectiveness of the method.

On a dissipative Gross-Pitaevskii-type model for exciton-polariton condensates
Ryan Obermeyer (University of Illinois at Chicago)
4:00 PM in 636 SEO
We study a generalized dissipative Gross-Pitaevskii-type model arising in the description of exciton-polariton condensates. We derive rigorous existence and uniqueness results for this model posed on the one dimensional torus and derive various a-priori bounds on its solution. Then, we analyze in detail the long time behavior of spatially homogenous solutions and their respective steady states. In addition, we will present numerical simulations in the case of more general initial data. We also study the corresponding adiabatic regime which results in a single damped-driven Gross-Pitaveskii equation and compare its dynamics to the one of the full coupled system.

Simulating Multilayer Plasmonic Devices with Domain Decomposition Methods: High-Order Perturbation of Surfaces Implementations
David Nicholls (University of Illinois at Chicago)
4:00 PM in 636 SEO
The faithful modeling of the propagation of linear waves in a layered, periodic structure is of paramount importance in many branches of the applied sciences, in particular, in the simulation and design of multilayer plasmonic devices. In this talk we present a novel numerical algorithm for the simulation of such problems which is free of the artificial singularities present in related approaches. We advocate for a non-overlapping domain decomposition method (DDM) phrased in terms of Impedance-Impedance Operators that are immune to the Dirichlet eigenvalues which plague the Dirichlet-Neumann Operators that appear in classical formulations. We demonstrate a High-Order Spectral algorithm to simulate these operators based upon a High-Order Perturbation of Surfaces methodology which is rapid, robust, and highly accurate. We demonstrate the validity and utility of our approach with a sequence of numerical simulations.
