Abstract
The quasiparticle structure of YBa2Cu3O7 is calculated within several approximations to the self-energy (RPA, ERPA, Hubbard I) and the model potential LDA+AMF. The partial DOS and distribution of holes yielded by the different approaches are presented and compared with available experimental data.
