Abstract:
In this talk, we will discuss the construction of KP hierarchies with constraints under the scheme of loop group. Matrix representations of corresponding pseudo-differential operators are given. To illustrate this process, we will give an example which is a generation of the constraint KP. Darboux transformation is constructed and formulas connecting Tau functions and formal inverse scattering solutions are given.
