The norm of H is asymptotically given by the maximum of the support of the self-consistent density of states. We establish a bound on this maximum in terms of norms of powers of S that substantially improves the earlier bound 2∥S∥1/2∞ given in [O. Ajanki, L. Erdős and T. Krüger, Universality for general Wigner-type matrices, Prob. Theor. Rel. Fields169 (2017) 667–727]. The key element of the proof is an effective Markov chain approximation for the contributions of the weighted Dyck paths appearing in the iterative solution of the corresponding Dyson equation."}],"year":"2018","ec_funded":1,"month":"09","publication_identifier":{"eissn":["2010-3271"],"issn":["2010-3263"]},"main_file_link":[{"url":"https://arxiv.org/abs/1802.05175","open_access":"1"}],"project":[{"call_identifier":"FP7","name":"Random matrices, universality and disordered quantum systems","_id":"258DCDE6-B435-11E9-9278-68D0E5697425","grant_number":"338804"}],"quality_controlled":"1","title":"Bounds on the norm of Wigner-type random matrices","date_published":"2018-09-26T00:00:00Z","citation":{"apa":"Erdös, L., &#38; Mühlbacher, P.
