    The longest excursion of a random interacting polymer
    (Berlin : Weierstraß-Institut für Angewandte Analysis und Stochastik, 2011) Köcher, Janine; König, Wolfgang
    We consider a random N-step polymer under the influence of an attractive interaction with the origin and derive a limit law -- after suitable shifting and norming -- for the length of the longest excursion towards the Gumbel distribution. The embodied law of large numbers in particular implies that the longest excursion is of order log N long. The main tools are taken from extreme value theory and renewal theory.
