Abstract
Within a simple and natural tight-binding model, we show that the increase in critical temperature from (or with ) to Y can easily be explained by the increase in density of states due to the CuO chains present in Y . We discuss the effects of moving the Fermi energy and shifting the chain band with respect to the plane bands.
