MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

A Variational Principle in Discrete Space-Time - Existence of Minimizers

Felix Finster

Abstract

We formulate a variational principle for a collection of projectors in an indefinite inner product space. The existence of minimizers is proved under general assumptions.
