Generalized tensor structures of Kawaguchi spaces (Q1881807)

The author investigates generalized almost complex structures and almost product structures associated to the metrics of a Kawaguchi space. He proves that, for a Kawaguchi space, there exist families of six-parameter tensor almost complex structures and almost product structures associated to the Sasakian metric of the space, and finds expressions of structural tensors of these structures. He also derives conditions for the integrability of these structures and finds affine connections compatible with them.
