On some properties of almost-analytic tensors in an *O-space

  • Sumio Sawaki

We consider an *O-space which is a kind of almost-Hermitian space. There is stated a theorem, that is, in a compact *O-space a skew-symmetric covariant almost-analytic tensor is closed. From this theorem, we get many important properties of almost-analytic tensors in an almost-Kählerian space or a K-space and an interesting result related to the Lie derivative.
