The Moduli and enumeration seminar (formerly MMARGS) is a weekly reading seminar organized by Maria Gillespie, Renzo Cavalieri and myself.  Participants take turns speaking on topics they find interesting, usually loosely connected to moduli spaces, algebraic curves, and counting problems in algebraic geometry.  If you are interested in attending, please let me know and I […]

The Number Theory Lab will meet weekly on Thursdays at 1pm in Weber 201. Our first talk will be on Thursday, September 1. We will begin this semester with a series of talks “What is …?” introducing various topics in number theory at a beginning graduate student level. We especially encourage the incoming graduate students […]

Educ8's First Meeting of the Semester!   We’re a club for everything math education – math teaching practices, research, theory, and how to navigate a career in mathematics teaching and learning. At our first meeting, we'll do introductions and talk about the goals of the club this semester as well as do some math ed […]

Jedrzej Garnek will speak in Fragment: The main part of the talk will be from 3-3:50, then we will have a 10 minute break, then resume from 4-4:20 with more advanced material.

An introduction to topological combinatorics The chromatic number of a graph is the number of vertex colors needed so that adjacent vertices have different colors. In 1955, Kneser made a conjecture about the chromatic number of a certain family of graphs (now called Kneser graphs). This conjecture remained unproven for 23 years until Lovász gave […]

Title:Defining Persistence Diagrams for Cohomology of a Cofiltration Indexed Over a Finite Lattice Advisor: Dr. Amit Patel Committee: Dr. Mark Shoemaker, Dr. Dustin Tucker Persistent homology and cohomology are important tools in topological data analysis, allowing us to track how homological features change as we move through a filtration of a space. Original work in […]

The Buzz about BHZ: The Life and Times of Brauer's Height Zero Conjecture Mandi Schaeffer Fry Metropolitan State University of Denver In 1955, Richard Brauer, often regarded as the founder of modular representation theory, made one of the first of the so-called ``local-global'' conjectures in character theory and opened the door to an entire area […]

Advisor: Dr. Maria Gillespie Committee: Dr. Alexander Hulpke, Dr. Mark Shoemaker, Dr. Sudipto Ghosh Title: Generalized RSK for enumerating projective maps from $n$-pointed curves A recent result of Farkas and Lian in enumerative geometry arose in the study of linear series on curves. The theory of Schubert calculus leads to a natural combinatorial interpretation of […]

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 the lens of spectral graph theory. In particular, we will discuss what eigenvalues can tell you about a graph and introduce some other families of […]

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 University of Colorado in Boulder. The goal of the FRNTD is to provide a venue for faculty, graduate students, and undergraduates on the Front Range […]
