1. The Chevreton Superenergy Tensor in Einstein-Maxwell Spacetimes
Sammanfattning : In this thesis we investigate the superenergy tensor that was introduced by Chevreton in 1964 as an electromagnetic counterpart to the Bel-Robinson tensor for the gravitational feld.We show that in Einstein-Maxwell spacetimes with a source-free electromagnetic feld, the Chevreton superenergy tensor has many interesting properties.

3. The Lanczos potential, dimensionally dependent identities and algebraic Rainich theory
Sammanfattning : In this thesis three major topics are dealt with: the Lanczos potential, dimensionally dependent identities and algebraic Rainich theory.The Lanczos potential is a potential for the \Vey! curvature tensor or for a tensor v-·ith the same algebraic symmetries. LÄS MER
