Courant代数胚上的超复结构

Hypercomplex structures on Courant algebroids

Mathieu Stienon

摘要:

Courant代数胚上的超复结构统一了全纯辛结构和通常的超复结构。本文证明了Courant代数胚上超复结构的两种刻画的等价性,一种是用Nijenhuis伴随刻画的,另一种是用(几乎)无挠联络刻画的,其中三种复结构都是平行的.

英文摘要:

Hypercomplex structures on Courant algebroids unify holomorphic symplectic structures and usual hypercomplex structures. In this note, we prove the equivalence of two characterizations of hypercomplex structures on Courant algebroids, one in terms of Nijenhuis concomitants and the other in terms of (almost) torsionfree connections for which each of the three complex structures is parallel.
