Abstract
The quasiparticle approach for electronic structure calculations consi dering strong electron correlations is given. The exact diagonalizatio n of a multiband Hubbard Hamiltonian for a small cluster is combined w ith perturbation theory for intercluster hopping. The band structure o f paramagnetic and antiferromagnetic La2CuO4 are discussed.
