• Inversions for reduced words (Sami Assaf, USC)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    The number of inversions of a permutation is an important statistic that arises in many contexts, including as the minimum number of simple transpositions needed to express the permutation and, […]

  • Quandle coloring quivers (Sam Nelson, CMC)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    Given a finite quandle $X$, a set $S \subset \mathrm{Hom}(X,X)$ of quandle endomoprhisms, and an oriented knot or link $L$, we construct a quiver-valued invariant of oriented knots and links. […]

  • An Introduction to the Sato-Tate Conjecture (Edray Goins, Pomona College)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    In 1846, Ernst Eduard Kummer conjectured a distribution of values of a cubic Gauss sum after computing a few values by hand.  This was forgotten about for nearly 100 years until John von Neumann and Herman Goldstine attempted to verify the conjecture as a way to test the new ENIAC machine in 1953.  They found […]

  • State Polytopes of Combinatorial Neural Codes (Rob Davis, HMC)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    Combinatorial neural codes are 0/1 vectors that are used to model the co-firing patterns of a set of place cells in the brain. One wide-open problem in this area is […]

  • Turning probability into polynomials (Mark Huber, CMC)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    Moment generating functions (Laplace transforms) are a means for transforming probability problems into problems involving polynomials.  Here I will concentrate on the binomial distribution, and use the mgf to link […]

  • Weil sums of binomials: properties and applications (Daniel Katz, CSUN)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    We consider sums in which an additive character of a finite field F is applied to a binomial whose individual terms (monomials) become permutations of F when regarded as functions.  These Weil […]

  • The Bateman—Horn conjecture II: applications (Stephan Garcia, Pomona)

    Millikan 2099, Pomona College 610 N. College Ave., Claremont, CA, United States

    We begin with a review of the Bateman—Horn conjecture, which sheds light on the intimate relationship between polynomials and prime numbers.  In this expository talk, we survey a host of applications of the conjecture.  For example, Landau’s conjecture, the twin prime conjecture, and the Green—Tao theorem are all consequences of the Bateman—Horn conjecture.  Moreover, the […]
