## APPM Department Colloquium - Bernard Deconinck

Oct. 9, 2020

Bernard Deconinck, Professor and Chair of Applied Mathematics, University of Washington Pole dynamics of solutions of integrable equations Kruskal (1974) suggested that the dynamics of solutions of the KdV equation could be understood by examining how their pole singularities (complex x, real t) interact. I will review a biased history...

## APPM Department Colloquium - Philippe Naveau

Oct. 2, 2020

Philippe Naveau, Laboratoire des Sciences du Climat et de l'Environnement, IPSL-CNRS, France Detecting changes in multivariate extremes from climatological time series Joint work with Sebastian Engelke (Geneva University) and Chen Zhou (Erasmus University Rotterdam) Many effects of climate change seem to be reflected not in the mean temperatures, precipitation or...

## APPM Department Colloquium - Julie K. Lundquist

Sept. 25, 2020

Julie K. Lundquist, Dept. of Atmospheric and Oceanic Sciences and Fellow, Renewable and Sustainable Energy Institute at University of Colorado, Boulder Turbulence to turbine wakes: challenges in the atmospheric science of wind energy (that could benefit from applied mathematicians) As the world moves away from fossil fuels and towards more...

## APPM Department Colloquium - Michael D. Schneider

Sept. 18, 2020

Michael D. Schneider, Group Leader for Astronomy & Astrophysics Analytics, Physics Division, Lawrence Livermore National Laboratory Quantum Machine Learning using Gaussian Processes Quantum computers may be transformative for a variety of computational tasks. We are pursuing machine learning methods for near-term quantum devices that may show advantage over classical computers...

## APPM Department Colloquium - Béatrice M. Rivière

Sept. 4, 2020

Béatrice M. Rivière, Noah Harding Chair and Professor of Computational and Applied Mathematics, Rice University Diffuse Interface Methods for Two-Phase Flows in Digital Rock Modeling multicomponent flows in porous media is important for many applications relevant to energy and environment. Advances in pore-scale imaging, increasing availability of computational resources, and...

## APPM Department Colloquium - Persi Diaconis

Aug. 28, 2020

Persi Diaconis, Mary V. Sunseri Professor of Statistics and Mathematics, Stanford University ADDING NUMBERS AND SHUFFLING CARDS When numbers are added in the usual way, 'carries' accrue along the way. It is natural to ask 'how do the carries go?' Is there a carry 'about half the time? If there...

## Applied Math Colloquium - Lou Pecora

Feb. 28, 2020

Lou Pecora, Naval Research Laboratory Cluster Synchronization of Chaotic Systems in Complex Networks The concept of synchronized systems has been around for centuries with one of the earliest studies being on the synchronization of clocks by Christiaan Huygens in the mid 1700’s. By the mid 1900’s it was well-known how...

## Applied Math Colloquium - Owen Miller

Feb. 21, 2020

Owen Miller, Department of Applied Physics, Yale University Upper bounds to electromagnetic response via convexity, causality, and duality Nanophotonics, the study of light interacting with materials patterned at the scale of the wavelength, is developing at a rapid pace, with ever more materials, form factors, and structural degrees of freedom...

## Applied Math Colloquium - Laura Miller

Feb. 14, 2020

Laura Miller, Department of Biology, University of North Carolina - Chapel Hill Flow through the hairy appendages of small animals: The leaky rake to solid plate transition. Numerous small organisms that swim, fly, smell, or feed in flows at the mesoscale, where inertial and viscous forces are balanced, use branched,...

## Applied Math Colloquium - Bengt Fornberg

Feb. 7, 2020

Bengt Fornberg, Department of Applied Mathematics, University of Colorado Boulder Euler-Maclaurin without analytic derivatives We consider here the Euler-Maclaurin (EM) formulas in the context of approximating infinite sums. If the function to be summed can be integrated analytically, these formulas provide highly accurate asymptotic expansions for the difference between the...
