  • If a Statistical Model Predicts That Common Events Should Occur Only Once in 10,000 Elections, Maybe it’s the Wrong Model (Danny Ebanks, Cal Tech)

    Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United States

    Political scientists forecast elections, not primarily to satisfy public interest, but to validate statistical models used for estimating quantities of scholarly interest. Although scholars have learned a great deal from these models, they can be embarrassingly overconfident: Events that should occur once in 10,000 elections occur almost every year, and even those that should occur […]

  • Permutation Jones Polynomials (Sam Nelson, CMC)

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

    The Jones Polynomial is an important invariant of knots with applications in physics, quantum computation and more. In this talk I will introduce a family of generalizations of the Jones polynomial associated to permutations of finite sets and discuss their properties.

  • Claremont Topology Seminar: Puttipong Pongtanapaisan (Pitzer College)

    Roberts South 103 Roberts Hall South 103, Claremont McKenna College, E 8th St, Claremont, CA, United States

    Speaker: Puttipong Pongtanapaisan (Pitzer) Title: Introduction to Quantum Invariants of 3-Manifolds Abstract: The previous speakers showed us how to distinguish knots and links using techniques involving quantum groups. I will start by explaining briefly why 3-manifolds, much like the universe we live in, can actually be represented as knots and links with numbers assigned to […]

  • CCMS Colloquium: Distribution-Based Optimal Asset Selling — Sixian Jin (CSU San Marcos)

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

    Abstract: In this talk, we study the optimal timing of selling a risky asset within the distribution builder framework. Instead of specifying a utility function or risk-aversion parameter, this approach allows an investor to express preferences directly through a desired distribution of the selling price. Mathematically, the problem is closely related to the Skorokhod embedding […]

  • Bertini’s theorem for F-rationality (Austyn Simpson, Bates College)

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

    A classical principle in algebraic geometry is that a general hyperplane section of a variety should have singularities no worse than those of the variety itself. Over the complex numbers, […]

  • Claremont Topology Seminar: Jim Hoste (Pitzer College)

    Roberts South 103 Roberts Hall South 103, Claremont McKenna College, E 8th St, Claremont, CA, United States

    Speaker: Jim Hoste (Pitzer) Title: Enumerating 2-bridge knots Abstract: A new proof of an old theorem. This is joint work with Patrick D. Shanahan (Loyola Marymount University). _______ We especially welcome […]

  • CCMS Colloquium: Frobenius invariants — Austyn Simpson (Bates College)

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

    Abstract: Rings containing a finite field mathbb{F}_p (such as the ring of polynomials with coefficients in mathbb{F}_p) admit a map called the Frobenius homomorphism which sends every element to its […]

  • NT Learning Seminar — On the Conway-Schneeberger 15-Theorem (Austin Dong)

    NT Learning Seminar
    Burkle 12, Claremont Graduate University 1021 N. Dartmouth Ave., Claremont, United States

    We showcase On the Conway-Schneeberger Fifteen-Theorem. Presented by Austin Dong.

  • 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 […]
