Frustrated percolation: spin glasses and glasses

Antonio Coniglio

Physics Department Naples University , Italy

The properties of glasses and spin glasses are biefly reviewed, stressing the differences and the analogies between the two classes of systems. A simple geometrical model, which contains as essential ingredients geometrical frustration and connectivity, will be presented. The model, which is named frustratd percolation, in the bond version maps exactly on the spin glass model, while in the site version exhibits properties closely related to structural glasses.
