Informal Geometric Analysis Seminar

Department of Mathematics

University of Maryland

Fall 2012 - Spring 2013






Date: Tuesdays at 4:30pm (and some Thursdays).
Room: Mathematics Building 3206.

Organized by: Y.A. Rubinstein . .

The aim of this seminar is to attract graduate students to Geometric Analysis, through learning and research talks. All talks should be accessible to beginning graduate students who might have background either in PDE or in geometry, but not necessarily in both.

    Otis Chodosh (Stanford)
    An Introduction to Linearization Stability of the Scalar Curvature Map
  • The scalar curvature map is the map from metrics on a fixed manifold M to functions on M which maps a metric to its scalar curvature. One may ask about the regularity of the set of metrics with the same scalar curvature function. Is it a (finite dimensional?) manifold? What is its tangent space? We'll describe some answers to this question along with some consequences.

  • February 26, 2pm, room 0411 (note special time, room)
    Tamas Darvas (Purdue)
    An introduction to free boundaries and obstacle problems for the Laplacian
  • The purpose of this talk is to provide a very brief introduction to obstacle problems for the Laplacian. We will try to summarize the most basic techniques available in studying the regularity of the free boundary.

  • April 2, 2pm, room 3206 (note special time, room)
    Yi Wang (Stanford)
    Isoperimetric inequality and Q-curvature
  • Using the techniques of A_p weights, we study the relationships between the isoperimetric inequality with the Paneitz Q-curvature. We show a Fiala-Huber type isoperimetric inequality for higher dimensions in which the isoperimetric constant depends only on the integrals of the Q-curvature.

  • April 12, 3:15pm, room EGR 1202 (Calabifest)
    Simon Donaldson (Imperial)
    Kahler-Einstein Metrics, Extremal Metrics and Stability
