Dirac猜想的一个反例

A counter-example to a conjecture of Dirac

从约束Hamilton系统相空间中对称性分析 ,给出一个反例 .首次用正则Noether恒等式说明Dirac猜想失效 。

Based on the canonical symmetries of constrained Hamiltonian systems, a counter-example to a conjecture of Dirac is given. Using the canonical first Noether theorem and canonical Noether identities, we have shown that Dirac's conjecture fails in that example. There is no linearization of constraint in our treatment.
