In Lagrangian field theory the Dickey bracket is a canonical Lie bracket on conserved currents. Under the relation between conserved currents and infinitesimal symmetries of the Lagrangian the Dickey bracket lifts the canonical Lie bracket on infinitesimal symmetries to their associated conserved currents (Noether's theorem), exhibiting a Lie algebra extension.
The Dickey Lie bracket on conserved currents is due to
and is reviewed in
The statement that the Dickey bracket Lie algebra of currents is a central Lie algebra extension of the algebra of symmetries by de Rham cohomology of the jet bundle appears as theorem 11.2 in (Part II of)
