Abstract
We present results for a very simple model for the interaction of hole s and apical oxygen vibrations in high-T(c) cuprates, and discuss rela ted models which have been applied to the same problem. We find that t he existence of two oxygen Positions is a common feature - in the appr opiate parameter range - of these models. In this range the adiabatic approximation fails; besides, the solutions become unstable with respe ct to very small asymmetrization of the systems, which results in dopi ng and temperature dependent physical properties.
