報告摘要:
The discrete KP hierarchy is also known as the (l ? l′)-th modified KP hierarchy. Here in this lecture, we will consider the corresponding two–component generalization, called the two–component discrete KP (2dKP) hierarchy,where the corresponding Lax formulation is given by the Shiota method, this is using scalar Lax operators involving two difference operators Λ1 and Λ2. We also consider the 2dKP reduction corresponding to the loop algebras.
