The new world of infinite random geometric graphs.

The infinite random or Rado graph R has been of interest to graph theorists, probabilists, and logicians for the last half-century. The graph R has many peculiar properties, such as its categoricity: R is the unique countable graph satisfying certain adjacency properties. Erdös and Rényi proved in 1963 that a countably infinite binomial random graph is isomorphic to R.

An application of the equivariant localization formula in Sasaki geometry.

We apply an extension of the Duistermaat--Heckman Theorem to study the volume, the total scalar curvature and the Einstein-Hilbert functionals defined on the Reeb cone of a Sasaki manifold and prove that they are all proper. This implies that there exists a Reeb vector field with (transversal) Futaki invariant in any the Reeb cone.
