Abstract:
Using the bilinear formalism, we consider multicomponent and matrix Kadomtsev–Petviashvili hierarchies. The main tool is the bilinear identity for the tau function realized as the vacuum expectation value of a Clifford group element composed of multicomponent fermionic operators. We also construct the Baker–Akhiezer functions and obtain auxiliary linear equations that they satisfy.
Keywords:
matrix modified Kadomtsev–Petviashvili hierarchy, multicomponent fermion,
auxiliary linear problem.
