Abstract
Abstract Recent results in the theory of copper-oxide compounds are reviewed with emphasis on the nature of the normal state, quasiparticle excitations and pairing mechanisms. The numerical and analytical results for the models with strong electron correlations ( p — d and t — J models) are discussed. The importance of dynamical spin fluctuations in the metallic state is pointed out and pairing mechanisms due to antiferromagnetic paramagnons and lattice vibrations are considered.
