A class of nonautonomous coupled KdV systems.

A class of nonautonomous coupled Korteweg–de Vries (KdV) systems in (1+1) dimensions are considered for integrability classification. Integrability of the systems is associated with the existence of a certain recursion operator. Some new integrable nonautonomous two-component KdV systems are found. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
