“…This operator is known to define a quantum integrable system (this is proved in [28] for the caseñ = 1, but the result is expected to be true for arbitraryñ). Moreover, generalized kernel functions K N,Ñ ,M,M (x,x, y,ỹ) for this non-stationary deformed eCS equation are known [29]: they obey relations as in (28) but for deformed eCS operators H N,Ñ (x,x) and H M,M (y,ỹ), and κ = (N − M)g is replaced by (N − M)g −Ñ +M . We expect that, using these generalized kernel functions, the construction in the present paper can be generalized to find solutions of the deformed non-stationary eCS equation.…”
