Chern curvature (${\Theta }_D=D^2$)

The vector-bundle curvature of the unique metric-compatible holomorphic Chern connection is an endomorphism-valued form of type $(1,1)$. It is Dolbeault closed and represents the curvature Dolbeault class. Its trace gives normalized first-Chern forms, while its full endomorphism action enters the Lefschetz-Dolbeault curvature commutator.
