IAS Special Year 2017-2018: Analysis and Topology on Locally Symmetric Spaces
December 2018The subject of the special year was locally symmetric spaces. Examples of these highly symmetric objects are the hyperbolic geometries investigated by Bianchi in the 19th century (the first illustration (on the left) is from Bianchi’s 1893 paper) and a 6-dimensional space parameterizing all possible three-dimensional lattices up to rotation (the second illustration (on the […]

Minimizing P-Frame Energy
November 2018Figure 1. Projections of a configuration on the unit sphere in
, consisting of the coordinate axes and vertices of the inscribed hemicube; i.e., the black vertices of the cube in a black and white coloring with alternating order. The 64 total vertices of the 6-dimensional cube give 32 vertices of the hemicube; […]

Math careers in academia
October 2018What is like to live the life of a math professor? There are many answers to this question, and they very much depend upon the nature of the mathematician’s institution. A professor at a private research university will have a different set of responsibilities and priorities to one at a liberal […]

Undergraduate Proves a Conjecture in the Theory of Water Waves
September 2018Seung Wook So, an undergraduate participant in ICERM’s Spring 2017 program on “Singularities and Waves In Incompressible Fluids,” discovered a proof of a conjecture in the theory of water waves. The question of how steep traveling water waves can become has a long history, going back at least to Stokes [Sto47]. During the ICERM program, […]

Accelerating molecular dynamics to reach unprecedented simulation times with atomistic accuracy
September 2018Molecular dynamics (MD), the numerical integration of the equations of motions of atoms and molecules, is one of the most powerful tools available to materials scientists, chemists, and biologists, because it provides a fully resolved view of the spatio-temporal evolution of materials. Because of its unparalleled predictive power, MD is extensively used to understand and […]

Why Zebrafish (Almost) Always Have Stripes
August 2018Words by Jeff Grabmeier, Ohio State News, grabmeier.1@osu.edu One of the most remarkable things about the iconic yellow and blue stripes of zebrafish is that they reliably appear at all. Zebrafish begin life as transparent embryos, with three types of pigment cells on their skin. As they develop, the […]

Data-to-Born Transform for Imaging with Waves
August 2018Imaging medium properties with waves is ubiquitous in geophysical seismic exploration, medical ultrasound diagnostics, non-destructive evaluation and testing of structures, radar and sonar surveying, etc. Most commonly, one obtains an image by probing the medium of interest with wave pulses emitted and recorded by an array of sensors. Typically, the image is based on the […]

SAMSI Research Develops Improved Estimates of Ocean Heat Content Changes
June 2018Ongoing research at the Statistical and Applied Mathematical Sciences Institute (SAMSI) has produced improved estimates of ocean heat content leading to a better understanding of which regions of the ocean are warming up and which ones are cooling down. This animation shows monthly vertically integrated ocean heat content anomalies for 2007-2016 using data from Argo […]
