WebbWe present a study of Rainich-like conditions for symmetric and trace-free tensors T. For arbitrary even rank we find a necessary and sufficient differential condition for a tensor to satisfy the source-free field equation. For rank 4, in a generic case, we combine these conditions with previously obtained algebraic conditions to gain a complete set of … WebbIn this note it is shown that the algebraic Rainich conditions are inevitably the consequence of every Euler-Lagrange equation associated with each member of a special class of …
WebbThe algebraic Rainich conditions refer to the Ricci tensor, but this tensor can be replaced by other tensors. Penrose [ 3 ] and more recently Bergqvist and Lankinen [ 4 , 5 ] made an analogy from the Ricci tensor to the Bel-Robinson tensor B α β μ ν , a certain fourth rank tensor quadratic in the Weyl curvature, which also satisfies algebraic Rainich-like … Webb15 juni 2005 · We present a study of Rainich-like conditions for symmetric and trace-free tensors T.

WebbThe algebraic Rainich conditions for neutrino fields are obtained in terms of an algebraic classification of symmetric second-rank tensors. The differential Rainich conditions are also obtained for ail but one class of neutrino fields. The algebraic classification of symmetric second-rank tensors used here is compared to two previously published …
