Theoretical ideas and experimental results concerning high-temperature superconductors are reviewed. Special emphasis is given to calculations performed with the help of computers applied to models of strongly correlated electrons proposed to describe the two-dimensional Cu${\mathrm{O}}_{2}$ planes. The review also includes results using several analytical techniques. The one- and three-band Hubbard models and the $t\ensuremath{-}J$ model are discussed, and their behavior compared against… 
Theoretical prospects for high-temperature superconductors
Progress in the quest to understand the electronic basis for high-temperature superconductors is reviewed with emphasis on theories that make contact with experimental realities in copper oxides. Key
Strong Electron Correlation Effects in Copper Oxides
In developing the theory of the high-temperature superconductivity it is necessary to solve the two most important problems which are definitely interrelated: what is the nature of the normal state
