Title: Eigenvalues of the Laplacian on Berger spheres

Speaker: Mustafa Kalafat

Abstract:

Berger spheres are introduced by Marcel Berger. These are
odd-dimensional spheres, which are squashed in a direction. The
shrinking direction can be provided by the circle action on the
complex Euclidean space. In other words, it corresponds to shrinking
or expanding the Hopf circles in an odd dimensional sphere.
Consequently, the resulting Riemannian metric is different than the
round metric. In this seminar series, we understand the eigenvalues of
the Laplacian on Berger spheres.

We will be using the following resources.
