We develop a cavity method for the spherical Sherrington-Kirkpatrick model at high temperature and small external field. As one application we compute the limit of the covariance matrix for fluctuations of the overlap and magnetization.
Nous développons la méthode de la cavité pour le modèle sphérique de Sherrington-Kirkpatrick à haute température et champs externe faible. Nous illustrons la méthode par le calcul de la matrice de covariance des fluctuations des recouvrements et de la magnétisation.
Keywords: Sherrington-Kirkpatrick model, cavity method
