On the self-overlap in vector spin glasses

Abstract

We consider vector spin glass models with self-overlap correction. Since the limit of free energy is an infimum, we use arguments analogous to those for generic models to show the following: 1) the averaged self-overlap converges; 2) the self-overlap concentrates; 3) the infimum optimizes over paths whose right endpoints are the limit of self-overlap. Lastly, using these, we directly verify the equivalence between the variational formula obtained in [arXiv:2303.16284] and Panchenko's generalized Parisi formula in [Ann. Probab., 46(2):865-896].
