SFU Cosmology Seminars

Tuesday, 4 March 2014, 14:00 in P8445B

Prof. Thomas Kephart (Vanderbilt University)

Helicity conservation and generalized Beltrami fields
We'll start with a review of magnetic helicity and the related Beltrami equation and then provide relativistic and non-abelian generalizations. Gauge invariance, variational principles, conserved currents, the energy-momentum tensor and choice of boundary conditions elucidate the subject. Applications will be discussed.
