  2. Graduate Student Seminar Series: The pressure metric on quasi-Fuchsian space & Green's functions on minimal submanifolds

    Location: SLMath: Eisenbud Auditorium, Online/Virtual
    Speakers: Yifan Guo (University of California, Irvine), Frieder Jaeckel (Universität Bonn)

    Zoom Link

    Frieder Jäckel: The pressure metric on quasi-Fuchsian space

    Abstract: Quasi-Fuchsian space is a moduli space of certain hyperbolic 3-manifolds and it can be equipped with a metric, called the pressure metric, whose definition is inspired by the definition of the Weil-Petersson metric on Teichmüller space. We will discuss that the pressure metric on quasi-Fuchsian space has finite diameter, why this is interesting, and how it relates to the study of eigenfunctions. The talk is based on joint work with E. Fioravanti, U. Hamenstädt and Y. Zhang

     

    Yifan Guo: Green's functions on minimal submanifolds

    Abstract: We are going to discuss the following properties of Green's function on a minimal submanifold with singularities : lower and upper bounds, asymptotics near the pole and infinity as well as $C^{\alpha}$ convergence under convergence of minimal submanifolds. We show that the Green's functions on area-minimizing boundaries have all of the mentioned properties. We also have $L^p$ convergence of the Green's functions for converging multiplicity 1 stationary varifolds. Outside of these classes of minimal submanifolds, the properties may fail and we discuss the reasons and some examples.

  3. GMT and Minimal Submanifolds Seminar: Free boundary minimal surfaces: existence and regularity

    Location: SLMath: Eisenbud Auditorium, Online/Virtual
    Speakers: Martin Man-chun Li (The Chinese University of Hong Kong)

    Zoom Link

    Free boundary minimal surfaces are critical points to the area functional with respect to boundary-preserving deformations. Apart from being a natural Neumann boundary value problem for minimal surfaces, these objects also arise in many other geometric problems like the extremal Steklov eigenvalue problem studied in the celebrated work of Fraser and Schoen. In this talk, I will discuss the question of existence and regularity for free boundary minimal surfaces, focusing in particular on certain min-max constructions where tools from geometric measure theory play a major role.

  4. GSA Seminar: G_2-instantons on non-compact cohomogeneity one manifolds

    Location: SLMath: Eisenbud Auditorium, Online/Virtual
    Speakers: Izar Alonso Lorenzo (Rutgers University)

    Zoom Link

    G_2-instantons are a special kind of connections on a Riemannian 7-manifold,  analogues of anti-self-dual connections in 4 dimensions.


    I will start this talk by introducing G_2-instantons and their significance, and then describe new families of SU(2)^2-invariant G_2-instantons in cohomogeneity one manifolds with a coclosed G_2-structure.

  5. Flows Seminar: A Generalized Avoidance Principle for Mean Curvature Flow

    Location: SLMath: Eisenbud Auditorium, Online/Virtual
    Speakers: Alec Payne (Duke University)

    Zoom Link

    The avoidance principle says that two mean curvature flows of hypersurfaces remain disjoint if they are disjoint initially. In this talk, we will discuss several generalizations of the avoidance principle that allow for intersections between the two hypersurfaces. First, we show that the Hausdorff dimension of the intersection of two mean curvature flows is non-increasing over time. We then prove a dimension monotonicity result for self-intersections of immersed mean curvature flows. Next, we extend the intersection dimension monotonicity to a class of Brakke flows and level set flows, and we provide examples showing that this monotonicity fails for general Brakke flows. In the course of the proof, we obtain a localization result and an equivalence between non-fattening and non-discrepancy for level set flows with finitely many singularities. This is joint work with Tang-Kai Lee.

  6. Reading Seminar on Kahler_Einstein metrics and RCD spaces, Lecture 1: When are KE metric spaces RCD?

    Location: SLMath: Eisenbud Auditorium
    Speakers: Shih-Kai Chiu (Vanderbilt University)

    Gabor, Section 3

    P1 Prop 15 & Thm 16

    The purpose of these series of lectures is to explain a recent result of Gabor Székelyhidi [Szek24] ttps://arxiv.org/abs/2408.10747, which shows that many singular Kähler-Einstein (K-E) spaces are quasi-smooth non collapsed RCD metric spaces with interesting geometric features.  

    We shall focus on Section 3 of [Szek24], showing that the metric completion of a constant scalar curvature Kähler (cscK) approximable K-E space is a non collapsed quasi-smooth RCD space, and that the corresponding singular K-E metric is a Kähler current.

    Location: SLMath: Eisenbud Auditorium
    Speakers: Junsheng Zhang (University of California, Berkeley)

    Gabor, Section 4

    The purpose of these series of lectures is to explain a recent result of Gabor Székelyhidi [Szek24] ttps://arxiv.org/abs/2408.10747, which shows that many singular Kähler-Einstein (K-E) spaces are quasi-smooth non collapsed RCD metric spaces with interesting geometric features.

  1. ADJOINT 2025

    ADJOINT is a yearlong program that provides opportunities for U.S. mathematicians – especially those from the African Diaspora – to conduct collaborative research on topics at the forefront of mathematical and statistical research. Participants will spend two weeks taking part in an intensive collaborative summer session at SLMath. The two-week summer session for ADJOINT 2025 will take place June 30 - July 11, 2025 in Berkeley, California. Researchers can participate in either of the following ways: (1) joining ADJOINT small groups under the guidance of some of the nation's foremost mathematicians and statisticians to expand their research portfolio into new areas, or (2) applying to Self-ADJOINT as part of an existing or newly-formed independent research group ((three-to-five participants is preferred) to work on a new or established research project. Throughout the following academic year, the program provides conference and travel support to increase opportunities for collaboration, maximize researcher visibility, and engender a sense of community among participants.
