Abstract
The infinite-range four-state clock spin glass, in the presence of an arbitrary magnetic field, is investigated by the replica method. The a ppropriate replica-symmetry breaking scheme is discussed for this mode l. It is shown that two distinct Almeida-Thouless lines are possible, depending on the direction of the applied field. The full phase diagra m of the model, showing its instability regions, is presented and disc ussed.
