Abstract
A new Lax equation is introduced for the KP hierarchy which avoids the use of pseudo-differential operators, as used in the Sate approach. This Lax equation is closer to that used in the study of the dispersionless KP hierarchy, and is obtained by replacing the Poisson bracket with the Moyal bracket. The dispersionless limit, under which the Moyal bracket collapses to the Poisson bracket, is particularly simple.
