The typical properties of this line, a set of identities and inequalities among correlation functions, allow us to prove the replica symmetry i.e. the concentration of the order parameter. When the interaction structure is elliptic we rigorously compute the exact solution of the model in terms of a finite-dimensional variational principle and we study its properties.Physics, MathematicalPhysicsmulti-species spin glassnishimori linereplica symmetry82-xx82d30griffiths inequalitiesenergytext::journal::journal article::research article
