摘要:

通过计算对称生成元的Poisson括号代数,得到了2-形式$B$和双向量$θ$同时扭曲的Courant括号.它是柯朗括号的推广,包含了著名的Schouten-Nijenhuis括号和Koszul括号,以及一些新的星括号。我们给出解释的星括号作为各向同性子空间上的投影。

英文摘要:

We obtain the Courant bracket twisted simultaneously by a 2-form $B$ and a bi-vector $θ$ by calculating the Poisson bracket algebra of the symmetry generator in the basis obtained acting with the relevant twisting matrix. It is the extension of the Courant bracket that contains well known Schouten-Nijenhuis and Koszul bracket, as well as some new star brackets. We give interpretation to the star brackets as projections on isotropic subspaces.
