  • CCMS Colloquium: Manuel Reyes (UCI)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Manuel Reyes (UCI) Title: When XY is not equal to YX Abstract:  The commutative property of algebra states that the order of multiplication makes no difference: XY = YX. […]

  • From ICON to GenICON: In-Context Operator Learning with Uncertainty Quantification (Siting Liu, UCR)

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

    Abstract: I will introduce In-Context Operator Networks (ICON), a framework in which a single neural network learns solution operators for differential equations directly from a few prompted input-output examples at inference time, without any weight updates. ICON acts as a few-shot learner across forward and inverse problems for ODEs, PDEs, and mean-field control. I will […]

  • Coordinate ring of the universal centralizer via Demazure operators (Tom Gannon, UCR)

    Estella 2099

    One of the key objects used in Ngo's proof of the fundamental lemma is the group scheme of universal centralizers associated to a split reductive group G. In this talk, we'll discuss forthcoming work, joint with Victor Ginzburg, which describes the coordinate ring of the group scheme of universal centralizers in terms of the root datum of G using Demazure (or divided […]

  • CCMS Colloquium: Andrew Fiss (Michigan Technological University)

    Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United States

    CCMS Colloquium invites you to a talk by Andrew Fiss (Michigan Technological University) Title: “Singing American Math: College Traditions from Book Burnings to Observatory Parties, 1880s-1920s" Abstract:  “Singing Math” is a practice that linked American colleges of the late nineteenth and early twentieth centuries. A part of broader college singing traditions, it stood apart because of its […]

  • An Exact Algorithm for the Unanimous Vote Problem (Feyza Duman Keles, NYU)

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

    Abstract: Consider n independent, biased coins, each with a known probability of heads. Presented with an ordering of these coins, flip (i.e., toss) each coin once, in that order, until we have observed both a head and a tail, or flipped all coins. The Unanimous Vote problem asks us to find the ordering that minimizes […]

  • Voting on relations using pairs information (Michael Orrison, HMC)

    Estella 2099

    Many aggregation problems ask us to turn individual judgments into a single collective outcome. In this talk, we model each voter’s input as a relation on a set of alternatives, allowing pairwise comparisons to include strict preferences, ties, or incomparability. This perspective gives a common framework for median procedures and scoring methods, including several familiar […]
