Evolution systems with constraints in the form of zero-divergence conditions
V. V. Zharinov Steklov Mathematical Institute, RAS, Moscow, Russia
Abstract:
We study evolution systems of partial differential equations in the presence of consistent constraints having the form of a system of continuity equations. We show that in addition to possible conservation laws of the standard degree equal to the number of spatial variables, each such system has conservation laws whose degree is one less than this number. We begin by completely describing the conservation laws and symmetries of the system of continuity equations. As an example, we calculate the second-degree conservation laws for the classical system of Maxwell's equations (the number of spatial variables is three here).
Keywords:
evolution system, constraint, continuity equation, conservation law, lowest-degree conservation law.
