Dorfman括号的自然提升

微分几何 2019-06-26 v3

摘要

在本注记中,我们证明:对于流形 MM 上的向量丛 EETMETM\oplus E^* 上由 prTM\operatorname{pr}_{TM} 锚定且 EEMM 上向量丛的 Dorfman 括号,等价于从 Γ(TME)\Gamma(TM\oplus E^*)TETEETE\oplus T^*E\to E 的线性截面的提升,该提升将给定的 Dorfman 括号与 TETETE\oplus T^*E 截面上的 Courant-Dorfman 括号交织起来。这展示了 Courant-Dorfman 括号的普适性,并允许我们通过相应的提升来刻画传递 Dorfman 括号的扭曲和对称性。
