  • Initial Conditions and the Big Push (Daniel Velasquez, CMC)

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    This paper examines how initial conditions shape the long-run impact of large temporary shocks on economic geography. Using WWII supply contracts in the United States, we show that temporary spending […]

  • Lüroth semigroups of hyperelliptic curves over number fields (Jasmine Camero, Pomona College)

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    Let $C$ be a smooth, projective, geometrically integral hyperelliptic curve of genus $g \ge 2$ over a number field $k$. We investigate the structure of the $\mathbb{P}^1$-parameterized density degree set $\delta_{\mathbb{P}^1}(C/k)$ (equivalently, the Lüroth semigroup) for such curves, consisting of degrees arising from morphisms to $\mathbb{P}^1$. Building on foundational frameworks for parameterized points, we provide […]

  • 47 Lecture – Ismar Volić (Wellesley College)

    Argue Auditorium, Pomona College 610 N. College Ave., Claremont, CA, United States

    The mathematics of democracy, from theory to practice Mathematics has played a largely unseen role in democracy for centuries, influencing everything from how votes are counted to how political boundaries are drawn. Today, classical mathematical ideas are finding unexpected new applications, while unprecedented computational resources are opening new avenues for analyzing and improving democratic systems. […]

  • In-Context Kernel Ridge Regression with Transformers (Mingsong Yan, UCSB)

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    Large language models (LLMs) can use examples provided in a prompt to make predictions for new queries without updating their parameters, a capability known as in-context learning. In this talk, I will explore how transformers, the architectural backbone of many LLMs, can perform nonlinear kernel ridge regression (KRR). I will first present numerical observations showing […]

  • Models of elliptic curves with maximal 2-adic image subject to a rational 2-isogeny ( Roberto Hernandez, UC Irvine)

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    Let $E$ be a non-CM elliptic curve defined over $\mathbb{Q}$. We present models of curves that have 2-adic image as large as possible, given the constraint that they have a rational 2-isogeny. These curves are known to be generic, and one of the aims of this article is to make that fact explicit. Our techniques […]

  • CCMS Colloquium: Sharp Comparisons Between Sliced and Standard 1-Wasserstein Distances — Yi Wang (John Hopkins University)

    Burkle 16, Claremont Graduate University 1021 N. Dartmouth Ave., Claremont, CA, United States

    Abstract: Optimal transport describes the process of finding the most efficient way to move mass between two distributions. Wasserstein distance measures the minimal transportation cost achieved by that optimal plan. However, in higher dimensions, computing the Wasserstein distance becomes computationally expensive. The sliced Wasserstein distance offers an effective and efficient way to alleviate this burden. […]

  • GEMS November 7th Session

    Shanahan 3481, Harvey Mudd College 320 E. Foothill Blvd., Claremont, CA, United States

    This GEMS session will be facilitated by Professor Robert Sanchez from Harvey Mudd College. Title: Going with the flow: The Mathematics of Fluid Motion Abstract: Why can the depth of a river or the height of a wave tell us how fast it is moving? This lesson talks about the mathematics of fluid motion and […]

  • Applied Math Course Preview

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    Please join us for the course preview of upper division undergraduate and graduate Spring 2027 courses in the Applied Mathematical Sciences. Come hear from faculty about the exciting options this upcoming Spring in applied math, data science, probability, statistics, and financial mathematics. It’s a great opportunity to learn more, ask questions, and plan your schedule!

  • Entropy of probability bundles (Wai Yan Pong, Cal State Dominguez Hills)

    Estella 1021 (Emmy Noether Room), Pomona College Claremont, CA, United States

    This will be a sequel of my last ANTC talk on bundles of probability schemes. We introduce entropy for fiber bundles of probability schemes and higher-order entropy for hypercubes of bundles. This framework yields categorical proofs of several fundamental results about Shannon entropy and reveals correspondences between classical concepts in information theory and categorical concepts […]
