A Recursion Incursion Excursion Adam Buck University of Wisconsin-Milwaukee PhD Graduate Student “I will share some of my favorite examples of recursively defined objects. Mostly we will look at fun problems that happen to have recursive solutions. The goal of... Read More
The UW-Milwaukee Alumni Association presents; Master Chats: Climate Change and the Great Lakes FEATURING Mathematical Sciences Distinguished Professor, Dr. Paul Roebber "To many, climate change seems too remote or too small to affect current decisions. What many do not realize is... Read More
Quantum Mechanics: How does it work? William Langhoff University of Wisconsin-Milwaukee PhD Graduate Student “Many have heard about the strange phenomena of quantum mechanics. Pop-science writers often talk about ‘superposition of states’, ‘wave function collapse’, and ‘uncertainty’. In this talk,... Read More
Auslander's Theorem for Permutation Actions on Noncommutative Algebras Jason Gaddis Miami University Assistant Professor of Mathematics “Let G be a small finite group acting linearly on a polynomial ring A over an algebraically closed field of characteristic zero. A famous... Read More
Obstructions to Riemmanian Smoothings of a Locally CAT(0) Manifold Bakul Sathaye Ohio State University PhD Student “In this talk I will discuss obstructions to Riemannian smoothings of a locally CAT(0) manifold. I will focus on obstructions in dimension = 4... Read More
Street View Imagery Based High-Resolution and High-Accuracy Human-Environment Vegetation Mapping: How Green is our County? Jacob Beihoff & Adam Honts University of Wisconsin-Milwaukee Undergraduate Students “Measuring the amount of vegetation in a given area has long been accomplished using satellite... Read More
The Fundamental Group of the Menger Sponge and the Towers of Hanoi Hanspeter Fischer Ball State University Professor of Mathematics “The classical fractal known as the "Menger sponge" is what remains of a solid cube after drilling infinitely many (ever... Read More
Cube Complexes and their Growth Series Richard Scott Santa Clara University Professor “A cube complex Y is a geometric object constructed by gluing together Euclidean cubes along their faces. If G is the fundamental group of Y, then there is... Read More
