Number of saddle points of the energy surface in SK spin-glass
Abstract
The average number of energy saddle points in the infinite range using spin glass model, in the annealed approximation, is analytically estimated. The computation is an extension of the work of Bray and Moore about the average number of metastable states. The results of the numerical simulations in energy barriers in the SK model are summarized.
