We present an algorithm which enables us to state necessary and sufficient conditions for the solvability of generalized Hamilton-type equations of the form ι (X) ω=α on a presymplectic manifold (M,ω) where α is a closed 1-form. The algorithm is phrased in the context of global infinite-dimensional symplectic geometry, and generalizes as well as improves upon the local Dirac–Bergmann theory of constraints. The relation between our algorithm and the geometric constraint theory of Śniatycki, Tulczyjew, and Lichnerowicz is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
