DUAL METRICS AND NONGENERIC SUPERSYMMETRIES FOR A CLASS OF SIKLOS SPACE–TIMES
DUAL METRICS AND NONGENERIC SUPERSYMMETRIES FOR A CLASS OF SIKLOS SPACE–TIMES
The presence of Killing–Yano tensors implies the existence of nongeneric supercharges in spinning point particle theories on curved backgrounds. Dual metrics are defined through their associated nondegenerate Killing tensors of valence two. Siklos space–times, which are the only nontrivial Einstein spaces conformal to nonflat pp-waves are investigated with regard to …
