We briefly discuss some of our recent results in three areas, all related to issues concerning the electronic structure and fermiology of the high-Tc's. (i) First-principles band theory based computations of the electron-positron momentum density relevant for the interpretation of the positron annihilation (2D-ACAR) experiments; results for YBa2Cu3O7 are discussed. (ii) Another k-resolved spectroscopy where such first-principles comparisons between the computed and measured spectral intensitiesdoi:10.1016/b978-0-444-81993-2.50061-5 fatcat:xgmfup4bijemxfrwxmazriisfi
