    Symmetric powers of Hilbert modular forms and p-adic L-functions
    To a Hilbert modular form one may attach a p-adic analytic L-function interpolating certain special values.... (Show Abstract)

    Modularity of nearly ordinary 2-adic residually dihedral Galois representations
    We prove modularity of some two dimensional, 2-adic Galois representations over totally real fields that are nearly ordinary and that are residually dihedral.... (Show Abstract)

    The compatibility of Kisin modules for different uniformizers
    Kisin modules are very useful to understand lattices in semi-stable representations. The construction of Kisin modules depends on the fixed choice of an uniformizer of the base field....(Show Abstract)

    Euler systems for Rankin-Selberg convolutions of modular forms
    An Euler system is a certain compatible family of classes in the cohomology of a Galois representation, which play a key role in relating arithmetical properties of the representation to values of the associated L-function....(Show Abstract)

    The arithmetic of elliptic curves in towers of number fields
    We will give an overview of Iwasawa theory for elliptic curves and present a pair of convenient p-adic L-functions...(Show Abstract)

    Jared Weinstein
    (Boston University)

    p-divisible groups over OC
    Complex abelian varieties are classified by pairs (V, L), where V is a finite-dimensional complex vector space and L is a lattice in V equipped with a Riemann form. In this talk we discuss a p-adic analogue of this classical result....(Show Abstract)

    Moshe Adrian

    Hecke algebras, simple supercuspidal representations, and the local Langlands correspondence
    A well known result of Borel says that category of modules over the Iwahori-Hecke algebra of a semisimple p-adic group G describes the Bernstein component associated to the unramified principal series of G....(Show Abstract)

    Yeansu Kim
    (Purdue University)

    L-functions from Langlands-Shahidi method and the generic Arthur L-packet conjecture
    L-functions are very interesting tools that number theorists have been using since 18th century. Those also appear in the local Langlands conjecture.....(Show Abstract)

    Computing Hida families
    I will report on joint work with Rob Pollack, Evan Dummit, Marton Hablicsek, Lalit Jain, and Daniel Ross on explicitly computing Hida families using overconvergent modular symbols.....(Show Abstract)

    Wieslawa Niziol
    (University of Utah)

    Syntomic cohomology
    Recently Beilinson and Bhatt have developed a new approach to comparison theorems of p-adic Hodge Theory. I will show how it can be used to construct well-behaved syntomic cohomology.....( Show Abstract)

    Frobenius fields for elliptic curves
    Let E be an elliptic curve defined over Q. For a prime p of good reduction for E, let πp be the p-Weil root of E and Qp) the associated imaginary quadratic field generated by πp. In 1976, Serge Lang and Hale Trotter formulated a conjectural asymptotic formula.....( Show Abstract)
