Curvatures of real connections on Hermitian manifolds

Abstract: Let $(M,g,J)$ be a Riemannian manifold with a compatible integrable complex structure $J\in\mathrm{End}(T_\mathbb{R} M)$ and $\mathcal{A}<em>{g,J}$ be the space of real connections on $T</em>\mathbb{R} M$ preserving both $g$ and $J$. In this paper, we investigate the relationship between the geometry of real connections in $\mathcal{A}_{g,J}$ and that of Hermitian connections on $T<sup>{1,0}M$. In particular, we study the geometry of the real Chern connection $\nabla<sup>{\mathrm{Ch,\mathrm{R}}}$ on $(M,g,J)$, and obtain K\"ahler-Einstein metrics by using real Chern-Einstein metrics.
