The Painleve transcendents PI–PV and their representations as isomonodromic deformation equations are derived as nonautonomous Hamiltonian systems from the classical R‐matrix Poisson bracket structure on the dual space slR*(2) of the loop algebra slR(2). The Hamiltonians are obtained by composing elements of the Poisson commuting ring of spectral invariant functions on slR*(2) with a time‐dependent family of Poisson maps whose images are four‐dimensional rational coadjoint orbits in slR*(2). Each system may be interpreted as describing a particle moving on a surface of zero curvature in the presence of a time‐varying electromagnetic field. The Painleve equations follow from reduction of these systems by the Hamiltonian flow generated by a second commuting element in the ring of spectral invariants. © 1995 American Institute of Physics.
