英文摘要	Using the language of jet bundles, we generalize the definitions of Euler-Lagrange one-form and the associated cohomology which were introduced by Guo et al. [Commun. Theor. Phys. 37 (2002) 1]. Continuous and discrete Lagrange mechanics and field theory are presented. Higher order Euler-Lagrange cohomology groups are also introduced.
