We assume subexponential decay for the matrix entries of W and we choose λ∼1, so that the eigenvalues of W and λV are typically of the same order. Further, we assume that the density of the entries of V is supported on a single interval and is convex near the edges of its support. In this paper we prove that there is λ+∈ℝ+ such that the largest eigenvalues of H are in the limit of large N determined by the order statistics of V for λ&gt;λ+. In particular, the largest eigenvalue of H has a Weibull distribution in the limit N→∞ if λ&gt;λ+. Moreover, for N sufficiently large, we show that the eigenvectors associated to the largest eigenvalues are partially localized for λ&gt;λ+, while they are completely delocalized for λ&lt;λ+. Similar results hold for the lowest eigenvalues. "}],"intvolume":"       164","arxiv":1}
