H-扭Courant代数胚

H-twisted Courant algebroids

Melchior Grutzmann

摘要:

本文推广了Hansen-Strobl关于$H$ -扭柯朗代数胚的定义,使得雅可比恒等式的扭$H$在锚映射的核中是4-形式,并且在自然发生的外部共变导数下是闭的.我们给出例子,并定义了上同调。

英文摘要:

We generalize Hansen--Strobl's definition of $H$-twisted Courant algebroid such that the twist $H$ of the Jacobi identity is a 4-form in the kernel of the anchor map and is closed under a naturally occurring exterior covariant derivative. We give examples and define a cohomology.
