Abstract
The t-J model for strongly correlated electron systems is mapped onto a model with a generalised permutation operator. For a specific value of the ratio t/J this model in one space dimension is shown to be equivalent to that of Lai (1974) and can be solved by the Bethe ansatz. This special point corresponds to supersymmetric invariance of the Hamiltonian.Keywords
