    On the Invalidity of Dirac's Conjecture for A System with Singular Higher-order Lagrangian

      摘要
    • 摘要: 基于奇异高阶拉氏量系统的正则Noether定理和poincarè-Catan积分不变量,给出一个三阶微商的反例,其中约束未作线性化,提出Dirac猜想是无效的.

       

      Abstract: Based on the canonical Noether's theorem and Poincarè-Cartan integral invariant for a system with singular higher-order Lagrangian, we present a counterexample with 3-order derivatives in which there is no linearization of constraints for such system to show that Dirac's conjecture is invalid.
