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 ( 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.

Applications of hypercomplex automorphic forms in Yang-Mills gauge theories

Rolf Sören Kraußhar and Jürgen Tolksdorf


In this paper we show how hypercomplex function theoretical objects can be used to construct explicitly self-dual $SU(2)$-Yang-Mills instanton solutions on certain classes of conformally flat $4$-manifolds. We use a hypercomplex argument principle to establish a natural link between the fundamental solutions of $D \Delta f = 0$ and the second Chern class of the $SU(2)$ principal bundles over these manifolds. The considered base manifolds of the bundles are not simply-connected, in general. Actually, this paper summarizes an extension of the corresponding results of Gürsey and Tze on a hyper-complex analytical description of $SU(2)$ instantons. Furthermore, it provides an application of the recently introduced new classes of hypercomplex-analytic automorphic forms.
