Abstract
The electronic structure of Ba2YCu3O6.9 has been calculated using the linear augmented-plane-wave method. The results show strongly 2-dimens ional and 1-dimensional features in the energy bands. These give rise to competing charge density wave instabilities. We argue that the prox imity of these instabilities and the large electron-phonon matrix elem ents of the Fermi-level electrons make important contributions to the high T(C) of this material.
