Free energy in the mixed p-spin models with vector spins

Using the synchronization mechanism developed in the previous work on the Potts spin glass model, we obtain the analogue of the Parisi formula for the free energy in the mixed even p-spin models with vector spins, which include the Sherrington.Kirkpatrick model with vector spins interacting through their scalar product. As a special case, this also establishes the sharpness of Talagrand.s upper bound for the free energy of multiple mixed p-spin systems coupled by constraining their overlaps.
