TY - JOUR AU - Bracken, Paul PY - 2010 TI - Exterior Differential Systems for Higher Order Partial Differential Equations JF - Journal of Mathematics and Statistics VL - 6 IS - 1 DO - 10.3844/jmssp.2010.52.55 UR - https://thescipub.com/abstract/jmssp.2010.52.55 AB - The theory of exterior differential systems is applied to study integrability of a set of related partial differential equations expressed in the terms of differential forms using Cartan's method. The Camassa-Holm equation and the Degasperis-Procesi equations are special cases that are described by these exterior differential systems. Some conservation laws are obtained in the cases of the more relevant equations. A closed differential ideal is constructed for each case studied.
