Idea

Given a jet bundle $J^r E$ of jets of finite order $r \in \mathbb{Z}$, its variational sequence (Krupka 90) is a resolution of its constant sheaf of locally constant functions with values in the real numbers by a chain complex of quotient of sheaves of differential forms by combinations of contact forms and their de Rham differentials. (e.g. PRWM 15, section 2.2).

The variational sequence is a sub-sequence of the Euler complex as obtained from the theory of the variational bicomplex (Krupka 90, see e.g. PRWM 15,theorem 1).
