Geometric Interpretation of the Mixed Invariants of the Riemann Spinor
Barry M Haddow
Mixed invariants are used to classify the Riemann spinor in the case of Einstein-Maxwell fields and perfect fluids. In the Einstein-Maxwell case these mixed invariants provide info…

Purely Magnetic Spacetimes
Barry Haddow
Purely magnetic spacetimes, in which the Riemann tensor satisfies for some unit timelike vector , are studied. The algebraic consequences for the Weyl and R…
