## In Memoriam: Eugene Spiegel

We are saddened to report that our former colleague Eugene Spiegel passed away earlier this week. Gene obtained his PhD from MIT in 1965. After a post-doc at Caltech he joined UConn in September 1967 as an Assistant Professor. Gene supervised six doctoral dissertations at UConn and, along with some other colleagues, built up the […]

[Read More]## UConn Hosting MathCounts Competition

On Saturday, February 9, the Department of Mathematics will host the Eastern Chapter of the MathCounts competition. For many years this competition took place at the Coast Guard Academy, but the recent government shutdown made it impossible. UConn came to rescue and hope to host up to 230 mathletes this week. One of the teams […]

In this talk, we will discuss an abstract but simple family of homogeneous Boltzmann equations for which we can develop an existence theory in $L^p$, and we will see what happens in the limit as the Boltzmann equation transitions into the Landau equation.

in 2007, it has been studied extensively on Kahler manifolds, providing a new

approach to uniformisation. In this talk, we will discuss the Ricci iteration on

spheres that are equipped with transitive Lie group actions. Joint work with

Timothy Buttsworth (Queensland), Yanir Rubinstein (Maryland) and Wolfgang

Ziller (Pennsylvania).

In this presentation we will explore what chaos is in a mathematical sense and will look at several specific examples that illustrate the mystery of chaos. We will also look at chaos as it is observed in the world around us and discuss what lies ahead in this field.

In recent work, we seek to extend the extrapolation capabilities of our framework to arbitrarily long timescales by using the fast KMC models as a numerical integrator with a prediction-correction scheme. Our "leapfrog" approach has the potential to truly enable computational simulation to reach experimental timescales.

One can easily imagine a future in which MD simulations used for research are routinely archived and analyzed in order to add to and modify an existing repository of learned chemical reactions and reaction rates. This repository would form a "chemical genome" that can then be used to quickly simulate all kinds of new chemical systems. This data-driven approach has the potential to break through long-standing barriers in the accuracy versus system size and time scale tradeoff that is at the core of computational materials science.

Short Bio:

Qian Yang joined the Computer Science and Engineering Department at the University of Connecticut in August 2018 as an Assistant Professor. She received her PhD in Computational and Mathematical Engineering from Stanford University in January 2018, where she was a member of the Materials Computation and Theory Group advised by Dr. Evan Reed. She holds a B.A. in applied mathematics/computer science from Harvard College. Her research focuses on the development of machine learning and computational methods for the physical sciences, and her work has been published in journals such as Chemical Science, Energy & Environmental Science, among others, as well as in a book chapter.
