In this interview, Sherman Richter gives an account of his life as a Jewish Minnesotan and World War II veteran. He was born in 1924 to an Orthodox Jewish family in North Minneapolis. Richter discussed leaving North High early to enlist in the Marine Corps, being somewhat aware of the Jewish situation in Europe in the early 1940s. He was trained...

I will present a family of random (compact) integral operators which encode the distributions of the critically spiked 'hard edge' eigenvalues, i.e., the bottom of the spectrum of certain Wishart/Laguerre ensembles. A potential source of interest in these objects is that they posses degenerations which reproduce the known deformed Tracy-Widom la...

In RMT the hard edge refers to the scaling limits of the minimal eigenvalues for matrices of sample covariance type. In the classical invariant ensembles, the limit distributions are characterized by a Bessel kernel and an associated Painleve III equation (as opposed to the better known Airy kernel and Painleve II descriptions at the 'soft' edge...

Each of these three posters contains a piece of digital art and a description of an aspect of life during the COVID-19 pandemic. The first poster shows a cartoon drawing of a man and a deer with antlers, both lying with their heads on pillows, with a flashlight shining between them. The deer has a speech bubble above him that says: "I Didnt [sic...

Mathematics students learn a powerful technique for proving theorems about an arbitrary natural number: the principle of mathematical induction. This talk introduces a closely related proof technique called "path induction," which can be thought of as an expression of Leibniz's "indiscernibility of identicals": if x and y are identified, then th...

In this presentation, I will revisit current mechanistic views about the propagation of cortical spreading depressions using electrophysiological data from rats obtained by means of high-resolution microelectrode arrays (MEA). Firstly, I will discuss the existence of facilitation/adaptation mechanisms in the CSD propagation, potentially related ...

Motivated by practical applications, chiefly clinical trials, we study the regret achievable for stochastic multi-armed bandits under the constraint that the employed policy must split trials into a small number of batches. Our results show that a very small number of batches gives already close to minimax optimal regret bounds and we also evalu...

Recent advances in computational geometry and computational topology have made it possible to compute topological invariants of sets and functions from sample points. These types of data summaries provide new tools for preprocessing, summarizing and visualizing complex and even high dimensional data. As a result, the number and the variety of ap...

Dynamical systems with a coupled cell network structure arise in applications that range from statistical mechanics and electrical circuits to neural networks, systems biology, power grids and the world wide web. A network structure can have a strong impact on the behaviour of a dynamical system. For example, it has been observed that networks c...

For animals and machines alike, maintaining balance during flight is acrucial and demanding task. The need for airplane flight stability led toa schism between aviators who sought built-in, or passive, stability andthose who emphasized the need for active controls. How has this tensionplayed out for the first flyers, the insects? Our group combi...
