The association of non-local symmetries with conservation laws: applications to the heat and Burgers’ equations. (English) Zbl 1084.35075
Summary: We extend the definition of the association of symmetries of partial differential equations with conservation laws to the nonlocal case. It is shown that if a conservation law is associated to a symmetry, a part of its equivalence class is also associated to that symmetry. Applications to the linear heat equation, the potential Burgers’ equation and Burgers’ equation are given.
