Constraints of the KP hierarchy and the bilinear method
The authors consider generalized \(K\)-constraints of the KP hierarchy where the Lax operator \(L\) is forced to satisfy \(L^k_- = q \partial^{-1} r\). The purpose of this paper is to examine the effect of those constraints on the bilinear equations.
