On a spectral problem in magnetohydrodynamics and its relevance for the geodynamo

Stefani, F.; Tretter, C.

One of the most remarkable features of the geodynamo is the irregular occurrence of magnetic field reversals. Starting with the operator theoretical treatment of a non-selfadjoint dynamo operator, we elaborate a dynamical picture of those reversals which relies on the existence of exceptional spectral points.

Keywords: geodynamo; magnetohydrodynamics
