# An inhomogeneous Lax representation for the Hirota equation

@article{Fioravanti2016AnIL, title={An inhomogeneous Lax representation for the Hirota equation}, author={Davide Fioravanti and Rafael I. Nepomechie}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2016}, volume={50} }

Motivated by recent work on quantum integrable models without U(1) symmetry, we show that the sl(2) Hirota equation admits a Lax representation with inhomogeneous terms. The compatibility of the auxiliary linear problem leads to a new consistent family of Hirota-like equations.
