k-Parameter geodesic variations
Ioan Bucataru, Matias F. Dahl
Suppose is a semispray on a manifold . We know that the complete lift of is a semispray on with the property that geodesics of correspond to Jacobi fiel…
Non-dissipative electromagnetic medium with a double light cone
Matias F. Dahl
We study Maxwell's equations on a 4-manifold where the electromagnetic medium is modelled by an antisymmetric (2, 2)-tensor kappa with real coefficients. In this setting the Fresne…
A restatement of the normal form theorem for area metrics
Matias F. Dahl
An area metric is a (0,4)-tensor with certain symmetries on a 4-manifold that represent a non-dissipative linear electromagnetic medium. A recent result by Schuller, Witte and Wohl…
Determination of electromagnetic medium from the Fresnel surface
Matias F. Dahl
We study Maxwell's equations on a 4-manifold where the electromagnetic medium is described by an antisymmetric -tensor . In this setting, the Tamm-Rubilar tensor den…
