Virtual Trivalent Spatial Graphs . . . (Sherilyn Tamagawa)
Title: Virtual Trivalent Spatial Graphs and Virtual Niebrzydowski Algebras Speaker: Prof. Sherilyn Tamagawa Visiting Assistant Professor Pomona College Abstract: If you were given two tangled up circles of string, could you untangle one to look like the other without cutting and reattaching the string? How could you tell? Knot theory explores answers to these questions. In this […]
Applied Math Seminar — Manuchehr Aminian (Cal Poly Pomona)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesTitle: Traditional Applied Math, and then, Working with High Dimensional Biological Data Abstract: I will give an overview of my interests in two parts. The first part will be on passive tracer problems – with the goal of finding formulas of descriptive statistics (mean, variance, skewness) for a solute distribution advected by a smooth flow […]
Critical points of toroidal Belyi maps (Edray Goins, Pomona)
On ZoomA Belyi map $\beta: \mathbb{P}^1(\mathbb{C}) \to \mathbb{P}^1(\mathbb{C})$ is a rational function with at most three critical values; we may assume these values are $\{ 0, \, 1, \, \infty \}$. Replacing $\mathbb{P}^1$ with an elliptic curve $E: \ y^2 = x^3 + A \, x + B$, there is a similar definition of a Belyi […]

Interrupted Time Series Models for Assessing Complex Health Care Interventions (Maricela Cruz, PhD)
Zoom meeting , United StatesTitle: Interrupted Time Series Models for Assessing Complex Health Care Interventions Maricela Cruz, PhD Assistant Investigator Biostatistics Unit Kaiser Permanente Washington Health Research Institute Abstract: Assessing the impact of complex interventions on measurable health outcomes is a growing concern in health care and health policy. According to the 2018 Annual Review of Public Health, interrupted time […]
Applied Math Seminar — Leif Zinn-Brooks (HMC/Scripps)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesTitle: Circadian Rhythms in Multinucleate Cells Abstract: Circadian rhythms are among the most researched cellular processes, but limited work has been done on how these rhythms are coordinated between nuclei in multinucleate cells. I'll analyze a mathematical model for circadian oscillations in a multinucleate cell, motivated by mRNA and protein data from the filamentous fungus Neurospora crassa. Stochastic simulations of […]
New norms on matrices induced by polynomials (Angel Chavez, Pomona)
On ZoomThe complete homogeneous symmetric (CHS) polynomials can be used to define a family of norms on Hermitian matrices. These 'CHS norms' are peculiar in the sense that they depend only on the eigenvalues of a matrix and not its singular values (as opposed to the Ky-Fan and Schatten norms). We will first give a general overview behind […]
Topology Seminar — Matthew vonAllmen
Zoom meeting , United StatesTitle: Untying Knots with Neural Nets Abstract: Neural networks can transform 3-dimensional data in a manner reminiscent of an ambient isotopy. With some modifications, a neural network can be trained to manipulate the vertices of a knot while respecting its topological structure. We use the discrete Mo ̈bius energy as a loss function to incentivize […]
What we talk about when we talk about math (Prof. Lillian Pierce)
ZoomTitle: What we talk about when we talk about math Speaker: Prof. Lillian Pierce, Nicholas J. and Theresa M. Leonardy Professor of Mathematics at Duke University Abstract: In 1864, the mathematician J. J. Sylvester wrote: May not Music be described as the Mathematics of the sense, Mathematics as Music of the reason?...Thus the musician feels […]

Panel on Paths in Mathematics After Undergrad
ZoomPanelists: Tatiana Bradley, Michelle Goodwin, Isys Johnson, John Lentfer, and Matthew vonAllmen We will have a panel discussion with graduates from the Claremont Consortium who have taken different pathways after graduation. After introductions, there will be time for open questions from the audience. Afterward, breakout rooms will be open for a casual discussion with the panelists and […]
