In this short note we study unimodular gravity in Weyl-De Donder formalism. We find corresponding Hamiltonian and study consequence of the unimodular constraint on the conjugate covariant momenta. We also find covariant Hamiltonian for Henneaux-Teitelboim unimodular action and study corresponding equations of motion.

协变形式主义中的幺模引力
在这篇简短的文章中,我们研究了 Weyl-De Donder 形式主义中的单模引力。我们找到了相应的哈密顿量并研究了单模约束对共轭协变动量的影响。我们还找到了 Henneaux-Teitelboim 单模作用的协变哈密顿量并研究了相应的运动方程。
