PARAQUATERNIONIC MANIFOLDS AND MIXED 3-STRUCTURES
Preview AbstractIn this paper we review basic properties of manifolds endowed with paraquaternionic structures and mixed 3-structures. Also, we investigate the existence of mixed 3-structures on normal semi-invariant submanifolds of paraquaternionic Kähler manifolds.
CONFORMAL KILLING–YANO TENSORS ON HIGHER DIMENSIONAL SPACETIMES ENDOWED WITH SPECIAL STRUCTURES
Preview AbstractThe existence of conformal Killing-Yano tensors on higher dimensional spacetimes endowed with positive and negative mixed 3-Sasakian structures is investigated.
