约束场论中Chetaev与vakonomic公式的参数化变分法
Chetaev vs. vakonomic prescriptions in constrained field theories with parametrized variational calculus
摘要：
从可容许的Cheataev和vakonomic变化的场论与约束的特征，我们展示了如何所谓的参数化变分法可以帮助导出vakonomic和非完整场方程。我们提出了一个例子，在场论的非完整方法被证明是非物理的。
英文摘要：
Starting from a characterization of admissible Cheataev and vakonomic variations in a field theory with constraints we show how the so called parametrized variational calculus can help to derive the vakonomic and the non-holonomic field equations. We present an example in field theory where the non-holonomic method proved to be unphysical.
