Lagrangian formalism and the intrinsic geometry of PDEs
arXiv:2211.15179 · doi:10.1016/j.geomphys.2023.104848
Abstract
A notion of internal Lagrangian for a system of differential equations is introduced. A spectral sequence related to internal Lagrangians is obtained. A connection between internal Lagrangians and presymplectic structures is investigated. An interpretation of the term of Vinogradov's -spectral sequence is given for irreducible gauge theories.
