"A function field analogue of Landau's theorem"

A famous theorem of Landau classifies the numbers which can be written as the sum of two squares and provides the asymptotic density of such numbers in the set of integers. In this talk, we will be looking at a function field analogue due to Soroker, Smilansky and Wolf.

This seminar will be held jointly online and in person:

"Betti numbers of nearly G2 manifolds"

On a Riemannian manifold there is a Weitzenböck identity which is a relationship between the Laplacian, the Bochner Laplacian and the curvature. We will consider this formula in the nearly G_2 setting and see how bounds on the Weyl Tensor or Sectional Curvature can give us certain information about the Betti numbers.
