Bonome, Agustín; Castro, Regina; García-Río, Eduardo; Hervella, Luis M. On the holomorphic sectional curvature on an indefinite Kähler manifold. (English. Abridged French version) Zbl 0765.53051 C. R. Acad. Sci., Paris, Sér. I 315, No. 11, 1183-1187 (1992). Summary: It is shown that for a general indefinite almost Hermitian manifold boundedness on the holomorphic sectional curvature leads to spaces of pointwise constant holomorphic sectional curvature. A family of null holomorphically flat indefinite Kähler manifolds but not of constant holomorphic sectional curvature is exhibited. Finally, we provide two criteria for the constancy of the holomorphic sectional curvature.
