Abstract:
We describe two modules for the algebra $P\!sd$ of pseudodifferential operators; for each of them, we define an associated system from which the Lax equations of the strict KP hierarchy can be obtained as compatibility conditions. We construct a set of bilinear equations on these modules that characterizes solutions of the strict KP hierarchy that are obtained by dressing the basic generator of $P\!sd$.
Keywords:
integrable deformation, pseudodifferential operator,
compatible Lax equation, strict KP hierarchy, dual wave function,
bilinear form.
