The symmetry analysis of electronic states in antiferromagnetic phase is applied to Cu02plane of High-To materials. The various allowed states are analyzed for characteristic points at the magnetic Brillouin zone boundary. The results show the way to discriminate experimentally between the two main

A model for HTSC is considered where electrons in the CuO2 planes belong to two separate groups: (a) those localized on Cu atoms with single occupation due to a large Coulomb interaction; and (b) conduction electrons in bands formed from p states of oxygens with direct oxygen-oxygen overlap.

A new mean-field approximation is proposed for the sandpile model of Bak, Tang and Wiesenfeld and the distribution of heights in the self-organized critical state is calculated. We treat several series of successive topples to approximate various avalanches. In contrast to the previous mean-field th
