Current Seminars

  1. Algebraic Geometry colloquium: Bott vanishing for algebraic surfaces

    Location: MSRI: Simons Auditorium
    Speakers: Burt Totaro (University of California, Los Angeles)

    Bott proved a strong vanishing theorem for sheaf cohomology on projective space. The statement does not hold for most varieties, and we survey what is known. We find new varieties that satisfy Bott vanishing, building on our knowledge of moduli spaces of K3 surfaces.

Upcoming Seminars

  1. Reading Group on Hodge Theory: The tautological bundle and its deformation properties

    Location: MSRI: Baker Board Room
    Speakers: Arend Bayer (University of Edinburgh)

    A moduli space of stable sheaves on an abelian surface carries a tautological sheaf, that plays a key role in Markman's result on the monodromy of generalised Kummer varieties, and his proof of the Hodge conjecture for Weil type abelian fourfolds. This talk will explore some of its key properties, in particular its deformation property as a hyperholomorphic sheaf, both along deformations of the generalised Kummer and its intermediate Jacobians.

  2. BGMS Seminar: Twistor path connectivity for complex tori

    Location: MSRI: Simons Auditorium
    Speakers: Elham Izadi (University of California, San Diego)

    The twistor path connectivity of the moduli spaces of irreducible hyperk”ahler manifolds was used in Verbitsky’s proof of the generic Torelli Theorem. Here, in joint work with Nikolay Buskin, we prove twistor path connectivity for the moduli spaces of complex tori.

  3. Elliptic Cohomology Learning Group: Deformation theory of derived stacks

    Location: MSRI: Simons Auditorium
    Speakers: Mauro Porta (Université de Strasbourg)

    In this talk I will discuss more at length the notions of being infinitesimally cohesive, nilcomplete and having a cotangent complex for a spectral stack. I will consider the specific example of the functor of deformations of a smooth and proper algebraic variety.

  4. Graduate Student Seminar

    Location: MSRI: Baker Board Room
    Created on Feb 22, 2019 01:38 PM PST
  5. What in the world is a spectrum? (#2) Frobenius and the Tate diagonal

    Location: MSRI: Simons Auditorium
    Speakers: Kirill Salmagambetov (Higher School of Economics)

    In his announcement of the seminar Hiro mentioned that one can view Frobenius map in positive characteristic as a stable homotopy theory phenomena. In my talk I will explain what this statement really means and why it turns out to be a purely “spectral” phenomena which does not exist on the level of chain complexes. As an application, I will define topological Hochshild homology of commutative rings with the cyclotomic structure on it and hopefully explain its relevance to arithmetic algebraic geometry.

    Created on Mar 18, 2019 10:54 AM PDT
  6. DAG Seminar: p-adic curves

    Location: MSRI: Simons Auditorium
    Speakers: Pierre Colmez (Institut de Mathématiques de Jussieu)

    We will explain how to decompose a p-adic curve in a way reminiscent to the pants decompositions of Riemann surfaces, and how to use this to compute the cohomology of p-adic curves.
