On the Support of Minimizers of Causal Variational Principles
Dr. Daniela Schiefenreder (Universität Regensburg)
We consider a class of causal variational principles where an action is
minimized for a Borel measure on a compact manifold. It can be
shown that under general assumptions the support of a minimizing
measure is either completely timelike, or it is singular in the sense
that its interior is empty. We consider numerical and analytical
studies on examples on the sphere which show that a phase
transition between completely timelike minimizers and singular
measures occurs. Moreover, we get a connection to packing problems
and the Tammes distribution.
This is joint work with F. Finster.
