Abstract

A Hamiltonian system in two dependent variables is presented with properties analogous to the Hamiltonian systems associated with the six Painlevé equations. Its solutions are meromorphic functions in the complex plane having only simple poles with three possible residues given by the third roots of unity. Like the Painlevé equations P_I - P_VI the system has families of rational solutions that can be obtained by applying Bäcklund transformations to certain seed solutions.
