In the previous talks of this series we met the Kneser graph and the character theory of finite groups. In this talk we will revisit these topics, this time through […]

We are excited to announce that the University of Colorado, Boulder and Colorado State University, Fort Collins will be hosting Front Range Number Theory Day on October 8th, 2022, at […]

Speaker: Facundo Mémoli from Ohio State University Title: Gromov-like distances between spheres Abstract: Distances between metric spaces such as the Gromov-Hausdorff distance and its Optimal Transport variants are nowadays often invoked in […]

Title: Singular Flavors of Compressive Sensing Abstract: About fifteen years ago, a couple of groundbreaking papers revealed the possibility of faithfully recovering high-dimensional signals from far fewer measurements than expected. […]

This Thursday's Fragment seminar speaker will be our own Clayton Shonkwiler, speaking on Frames, Geometric Invariant Theory, and Optimization.

Department of Mathematics, Texas A&M University Paper Folding: Modeling, Analysis and Simulation The unfolding of a ladybird's wings, the trapping mechanism used by a flytrap, the design of self-deployable space […]

Advisor: Dr. Jeff Achter Committee:  Dr. Rachel Pries, Dr. Jamie Juul, Dr. Indrajit Ray Title: Explicit and quantitative results for abelian varieties over finite fields Abstract: Given an elliptic curve […]

Title: Time Integration Methods and Software for Scientific Simulations Abstract: Time-dependent systems are at the heart of numerous scientific applications requiring simulation.  While single rate, fixed step size time integration […]

Polytopes count (introductory talk) Aram Bingham Colorado School of Mines We'll see how many problems in combinatorics can be converted to the problem of counting integral points inside appropriate polytopes. […]

Expander graphs arising from finite groups Martin Kassabov Cornell University Informally, expander graphs are  graphs which can not be easily disconnected.  In the case of bounded degree, this property is […]
