Several different models have recently been proposed to explain High Temperature Superconductivity. This book gives an authoritative and up-to-date review of two such proposals, namely the Hubbard and Anyon Models. This invaluable reference is a must for all physicists interested in the fast-paced revolutionary field of High Temperature Superconductivity.
