Abstract
We give the q-deformed analogue of a recently introduced electron mode l which generalizes the Hubbard model with additional correlated hoppi ng terms and electron pair hopping, The model contains two independent parameters and is invariant with respect to the quantum superalgebra U-q(gl(2/1)), It is shown to be integrable in one dimension by means o f the quantum inverse scattering method.
