李群余切丛中的修正辛结构

Modified symplectic structures in cotangent bundles of Lie groups

F. J. Vanhecke, C. Sigaud, A. R. da Silva

摘要:

在较早的工作(*)中,我们研究了仿射空间${\cal Q}={\bf R}^N$的余切丛中的正则辛结构的一个扩展,通过附加项暗示了位形变量和动量变量的泊松非交换性。在这篇文章中,我们声称,这样的扩展可以做一致时,${\cal Q}$是李群$G$。--(*):F.J.Vanhecke,C.Sigaud and A.R.da Silva,arXiv:math-phys/0502003 and Braz.J.Phys. { \bf 36},无IB,194(2006)

英文摘要:

In earlier work (*) we studied an extension of the canonical symplectic structure in the cotangent bundle of an affine space ${\cal Q}={\bf R}^N$, by additional terms implying the Poisson non-commutativity of both configuration and momentum variables. In this article, we claim that such an extension can be done consistently when ${\cal Q}$ is a Lie group $G$. -- (*) : F.J.Vanhecke, C.Sigaud and A.R.da Silva, arXiv:math-phys/0502003 and Braz.J.Phys.{\bf 36},no IB,194(2006)
