Title: Knots and their complements
Abstract: One way to study a knot in three-dimensional space is by looking at the topology of the complement. For knots in the three-sphere, Gordon and Luecke proved that the topology of the knot complement completely determines the knot. We will discuss generalizations of this idea to some other settings.

Battle of the Bands: Using R Shiny to Disentangle Contributions in Indie Rock Collaborations

William Cipolli
Colgate University

Abstract: The Data Science Collaboratory at Colgate University addresses the gap in statistical research support common at smaller institutions. To empower instructors, students, and the broader research community, we developed R Shiny web applications that facilitate technically sound analyses paired with foundational learning materials and case studies. We will discuss one such case study where we analyze the music and lyrics of three collaborating indie rock bands to understand their individual contributions, including data collection, ethical considerations, and results that align with publicly available information.

Bio: Dr. Cipolli is an Associate Professor of Mathematics at Colgate University. He specializes in Bayesian nonparametric statistics and develops flexible approaches to modern statistical problems. As the cofounder of Colgate's Data Science Collaboratory, Will collaborates on diverse projects across Biology, Psychology, and Sociology, and he is a lead developer of R Shiny applications for both statistical analysis and education.

Title. GAN: Dynamics and Mode Collapse

Abstract. Generative Adversarial Networks (GANs) were among the first machine learning algorithms capable of producing remarkably realistic synthetic data. In this talk, we focus on a simplified, toy setting that exposes the core mechanics of the GAN algorithm and its connection to optimal transport theory. We show how, in shallow architectures, GAN training can be interpreted as an approximation of an underlying system of partial differential equations. Within this reduced framework, we analyze a concrete toy example that exhibits pathological behavior analogous to mode collapse. This example illustrates how the PDE viewpoint clarifies the dynamical mechanisms responsible for non-convergence and instability in GAN training.

Colloquium

The math department hosts a colloquium series in which distinguished researchers present their recent work to a general mathematical audience.  All faculty, graduate students and undergraduate students are welcome.

Organizer: Jeremiah Birrell

Algebraic Combinatorics Reading Seminar

This seminar meets about once a week.  The format is very informal, the idea is that we collectively select a topic for the semester and present material surround that theme.  Original research is not typically presented and we encourage participation from all levels. Graduate students with an interest in algebra/combinatorics are especially encouraged to attend. 

For more information or to be included in communication regarding this seminar please contact Anton Dochtermann.

Differential Equations and Applied Math Seminar (DEAM)

The Differential Equations and Applied Math Seminar is a seminar for those interested in differential equations, mathematical modeling, mathematical physics, scientific computation, and any other interdisciplinary mathematical work of an applied nature.  The speaker's topics are not restricted to their own work, as this seminar is a platform for presenting details of mathematics of interest.  Interested faculty, graduate students, and advanced undergraduates are encouraged to attend.

Organizers: Ray Treinen & Nestor Guillen

Discrete Math Seminar

All faculty, graduate students, and upper level undergraduate students are welcome. The seminar will provide a platform for faculty and students to present their research developments in discrete mathematics and related areas, foster research interactions among faculty and students, and create research opportunities and collaborations for faculty and students. Speakers from Discrete Mathematics, Combinatorics, Computer Science, and other related areas are all welcome. We are particularly interested in interdisciplinary research which applies mathematics as a tool to solve problems in other areas such as CS, BioInformatics, Bio‐sciences, Engineering, Physics, Chemistry, etc.

Organizer: Jian Shen

Logic@TXST logo

Logic@TXST

This is a program designed to encourage research into mathematical logic at Texas State University and both the undergraduate and faculty levels, first by bringing in logic speakers to stimulate interest, and then fund subsequent research.

Times and locations of these talks will vary.

Organizer: Will Boney

Machine Learning Reading Seminar

In this seminar we learn about the mathematical foundation of this technology and their rapidly expanding use in our world.
All interested faculty, staff, and undergraduate and graduate students are welcome.

Organizer: Christine R.S. Lee

Talk Math 2 Me logo

Talk Math 2 Me

This is a seminar for students by students. Talk Math 2 Me provides students, both graduate and undergraduate, an opportunity to present anything related to mathematics to an audience of their peers. Undergraduate and Graduate math students or any students interested in mathematics are highly encouraged to attend. The talks are each 15‐60 minutes long and possible speaking topics include Undergraduate and Graduate mathematics research, math history, and STEM research with a heavy footing in mathematics.

Math & Stats Awareness Month

In April, the math department runs a series of annual presentations aimed at illuminating interdisciplinary connections between mathematics and other areas. We host guest speakers, partner with other departments within the university and invite panelists whose work relates to the presented themes. All presentations are geared toward the general audience. Everyone is invited.

Organizer:  Hiroko Warshauer
