Geometric Interpretation of the Mixed Invariants of the Riemann Spinor
GEOMETRIC INTERPRETATION OF THE MIXED INVARIANTS OF THE RIEMANN SPINOR Barry M Haddow ?School of Mathematics Trinity College Dublin 2IRELAND February 7,2008Abstract Mixed invariants are used to classify the Riemann spinor in the case of Einstein-Maxwell ?elds and perfect ?uids.In the Einstein-Maxwell case these mixed invariants provide information as to the relative orientation of the gravitational and electromagnetic principal null directions.Consideration of the perfect ?uid case leads to some
