退化Lagrange系统的KT-BRST复形

The KT-BRST complex of a degenerate Lagrangian system

D. Bashkirov, G. Giachetta, L. Mangiarotti, G. Sardanashvily

摘要:

拉格朗日场系统的量子化本质上取决于它的简并性,并意味着它的BRST扩展由非平凡的Noether恒等式和高阶Noether恒等式定义。然而,遇到一个问题,如何选择平凡和非平凡的高阶Noether恒等式。我们证明了在一定条件下,可以把由场、反场和鬼组成的KT-BRST复形与退化拉格朗日量L联系起来,这些复形的边界和上边界算子提供了L的所有非平凡Noether恒等式和规范对称性.在这种情况下,L可以扩展到主方程的适当的解决方案。

英文摘要:

Quantization of a Lagrangian field system essentially depends on its degeneracy and implies its BRST extension defined by sets of non-trivial Noether and higher-stage Noether identities. However, one meets a problem how to select trivial and non-trivial higher-stage Noether identities. We show that, under certain conditions, one can associate to a degenerate Lagrangian L the KT-BRST complex of fields, antifields and ghosts whose boundary and coboundary operators provide all non-trivial Noether identities and gauge symmetries of L. In this case, L can be extended to a proper solution of the master equation.
