Curvatures in Kähler varieties
Kähler, Ricci, holomorphic sectional curvature
In this work we will discuss the notion of curvature in the particular context of the Kähler varieties. We will study Ricci's curvature and show that in the case of the Kähler varieties this can be described by a particularly simple formula in complex coordinates.
We will also study the holomorphic sectional curvature, which is an analog of the sectional curvature in the real case, and which, as in the real case, characterizes the curvature tensor of the Kähler variety considered.
In addition, we will comment on the case where the holomorphic sectional curvature is constant and the corresponding classification.
