Rigidity and stability of Einstein metrics for quadratic curvature functionals
Wed 8 Jun 2011, 11:00am-12:00pm


 ABSTRACT: I will discuss rigidity (existence or nonexistence of

infinitesimal deformations) and stability (strict local minimization)

properties of Einstein metrics for quadratic curvature functionals on

Riemannian manifolds. This is joint work with Matt Gursky.

Consider the Poisson point process in Euclidean space. We are interested in functions on this random point set whose value in each configuration point is given by some ``local" rule (no ``central planning"). One example is the so-called allocation problem,
where we want to partition $\R^d$ to sets of volume 1 and match them with the point process, in a translation equivariant way. We want to make the allocated set optimal in some sense (e.g., the distribution of the diameter shows fast decay). We will present some allocation schemes, among them one with an optimal tail, which is our recent construction with R. Marko.
