摘要：

We have carried out first-principles angle-resolved photo-intensity computations in a number of high-T-c, compounds. This article provides an overview of some of the results of current interest in connection with the relevant photoemission data. Specific issues discussed are: (i) surface states in Nd2-xCexCuO4, (ii) extended van Hove singularity in YBa2Cu4O8 at the Y-point, (iii) signature of CuO2 plane bands in the cuprates, and (iv) constant initial state photoemission spectra.
