1-Manifolds Galore! Laurence Siebenmann University of Paris-SUD Professor of Mathematics “I will present a combinatorial classifcation, up to homeomorphism, of all simply connected, separable, non-Hausdorff, 1-dimensional manifolds (possibly with boundary), each having only finitely many singular points. These often occur... Read More
Automatic, Multiple Assessment Options in Undergraduate Math and Science Education Jonathon Kahl University of Wisconsin-Milwaukee Professor of Atmospheric Science “Since 2008, automatic, multiple assessment options have been utilized in selected undergraduate meteorology courses at the University of Wisconsin– Milwaukee. Motivated... Read More
Some Unitary Representations of R. Thompson's Groups F and T Vaughan Jones Vanderbilt University Stevenson Distinguished Professor Fields Medal Recipient “Thompson’s groups are groups of piecewise linear homeomorphisms of the interval and circle where all the non-smooth points are dyadic...

Some Questions in Harmonic Analysis Involving Curvature Betsy Stovall University of Wisconsin-Madison Assistant Professor of Mathematics “We will describe some open and recently solved questions in Harmonic Analysis where curvature plays a crucial role. In particular, we will discuss how... Read More
Wiener's Lemma and Applications Qiyu Sun University of Central Florida Professor of Mathematics “The classical Wiener's lemma states that if f(x) is a function with an absolutely convergent Fourier series, which nowhere vanishes for real arguments, 1/f(x) has an absolutely... Read More
Maximal Subgroups in Direct Products of Groups Dr. Dandrielle Lewis University of Wisconsin-Eau Claire Associate Professor of Mathematics “Given a direct product of groups, G and H, and information on the subgroups of G and H, what can one say... Read More
Borsuk-Ulam Type Theorems and Existence of Equilibria in Games with Incomplete Information Stanislaw Spiez Institute of Mathematics of the Polish Academy of Sciences “In 1968, R. Aumann, M. Mashler and R. Sterns proved that any undiscounted infinitely repeated two-person zero-sum... Read More
Entropy, Maximum Entropy, and the Maximum Entropy Method Jiu Ding University of Southern Mississippi Professor of Mathematics “We introduce the concepts of Shannon entropy and Boltzmann entropy, and we present Jaynes' maximum entropy principle. Then we apply this principle and... Read More
Divide and Conquer Algorithms for Large Hermitian Eigenvalue Problems Yousef Saad University of Minnesota Distinguished Professor of Computer Science “Divide-and-conquer paradigms can lead to efficient and flexible techniques for solving large Hermitian eigenvalue problems. This talk will discuss how these... Read More
