Conservation laws for even order systems of polyharmonic map type
Frédéric Louis de Longueville, Andreas Gastel
Following Rivière's study of conservation laws for second order quasilinear systems with critical nonlinearty and Lamm/Rivière's generalization to fourth order, we consider similar…

Canonical gauges in higher gauge theory
Andreas Gastel
We study the problem of finding good gauges for connections in higher gauge theories. We find that, for -connections in strict -gauge theory and -connections in -gauge…

Yang-Mills connections of cohomogeneity one on SO(n)-bundles over Euclidean spheres
Andreas Gastel
We construct Yang-Mills connections on SO(n)-bundles over spheres equipped with the Euclidean metric. We use a cohomogeneity one group action on the bundle to reduce the Yang-Mills…
