  2. 1. The Chevreton Superenergy Tensor in Einstein-Maxwell Spacetimes

    Author : Ingemar Eriksson; Göran Bergqvist; Paul Todd; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Einstein-Maxwell; graviational energy; superenergy; Bel tensor; Chevreton tensor; conservation laws; Conformal Einstein space; Theory of relativity; gravitation; Relativitetsteori; gravitation;

    Abstract : 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.

  5. 3. The Lanczos potential, dimensionally dependent identities and algebraic Rainich theory

    Author : Anders Höglund; José M. M. Senovilla; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE
