Abstract
The equilibrium properties of the Blume-Emery-Griffiths model with bilinear quenched disorder are studied for the case of
attractive as well as repulsive biquadratic interactions. The global phase diagram of the system is calculated in the context
of the replica symmetric mean field approximation.
