Hamiltonian multiform description of an integrable hierarchy
Vincent Caudrelier, Matteo Stoppato
Motivated by the notion of Lagrangian multiforms, which provide a Lagrangian formulation of integrability, and by results of the authors on the role of covariant Hamiltonian formal…

A connection between the classical r-matrix formalism and covariant Hamiltonian field theory
Vincent Caudrelier, Matteo Stoppato
We bring together aspects of covariant Hamiltonian field theory and of classical integrable field theories in dimensions. Specifically, our main result is to obtain for the f…
