analytic in a neighborhood of infinity will be approximated by Pade approximants. In a first group of results rather strong assumptions are made about the singularities of the function f to be approximated (Assumption 1.1). In a second group (Definition 1.3 and Theorem 1.7) a different type of assum
## Abstract We use ideas of Blackman et al. [4] for the coherent potential approximation (CPA) in alloys with configurationβdependent hopping terms. In the locator formalism the inverse self energy obeys an equation of the same form as the standard CPA equation. We first apply the formalism to the
