On Gauduchon connections with Kähler-like curvature
نویسندگان
چکیده
We study Hermitian metrics with a Gauduchon connection being "K\"ahler-like", namely, satisfying the same symmetries for curvature as Levi-Civita and Chern connections. In particular, we investigate $6$-dimensional solvmanifolds invariant complex structures trivial canonical bundle metrics. The results this case give evidence two conjectures that are expected to hold in more generality: first, if Strominger-Bismut is K\"ahler-like, then metric pluriclosed; second, another connection, different from or Strominger-Bismut, K\"ahler. As further motivation, show K\"ahler-like condition assures Ricci flow preserves along analytic solutions.

متن کاملExamples of Hyper - Kähler Connections with Torsion
The internal space of a N=4 supersymmetric model with Wess-Zumino term has a connection with totally skew-symmetric torsion and holonomy in Sp(n), i.e. a HKTconnection. We study the mathematical background of this type of connections and provide several examples to illustrate the theory.

CONNECTIONS, CURVATURE, AND p-CURVATURE
1.1. Connections and derivations. Let S be a scheme, and X smooth and finite type over S throughout. We have the rank-n vector bundle ΩX/S of 1-forms on X over S. We also fix some notation in the case that S is of characteristic p: in this case, we denote by FT the absolute Frobenius map for any scheme T , by X = X×S S the p-twist of X over S, where the map used in the fiber product is FS : S →...
