  1. EGN Polyfold Lab Meeting: Quotient of polyfolds and equivariant fundamental class

    Location: MSRI: Baker Board Room
    Speakers: Zhengyi Zhou (University of California, Berkeley)

    I will discuss how to apply polyfolds to equivariant problems. In particular, I will define the equivariant fundamental class in the polyfold setting. Combining with the polyfold construction for Gromov-Witten invariants by Hofer, Wysocki, Zehnder, this yields the construction for equivariant Gromov-Witten invariants using polyfolds. The main tool is the quotient construction for polyfolds.

  2. EGN Main Seminar: The Geometry of equivariant elliptic cohomology

    Location: MSRI: Baker Board Room
    Speakers: Nora Ganter (The University of Melbourne)

    I will give an introduction to the construction of equivariant elliptic cohomology and then talk about some recent geometric approaches to the subject.

  3. UC Berkeley Colloquium: p-adic algebraic K-theory and topological cyclic homology

    Location: 60 Evans Hall
    Speakers: Akhil Mathew (University of Chicago)

    http://events.berkeley.edu/index.php/calendar/sn/math.html?event_ID=115325

    Algebraic K-theory is a basic invariant of rings connected to deep phenomena in arithmetic, geometry, and topology. When one works with the p-adic K-theory of p-adic rings, the theory of trace maps and the apparatus of topological cyclic homology (TC) is often a highly effective approximation used in many computations. The theory TC, while more conceptually involved than K-theory, is often easier to work with. In this talk, I will give a gentle introduction to these theories and explain their applications to some new structural results in K-theory.

  4. EGN symplectic geometry and mirror symmetry seminar: Lagrangian tori in CP^2

    Location: 748 Evans Hall
    Speakers: Renato Ferreira de Velloso Vianna (Center for Mathematical Sciences)

    We will present an infinite series of monotone Lagrangian tori in CP^2, which arise as fibres of almost toric fibrations (ATFs). We show how to distinguish these tori up to the action of Symp(CP^2). Time permiting, based on a joint work with Tonkonog and Shelukhin, we will present (a 4-dimensional version) of an invariant for any Lagrangian, and use it to determine the space of almost toric fibres modulo the action of Symp(CP^2).
