Title: A disordered system, a recursion relation, extreme value statistics and random measures. Abstract: We study a disordered system through a recursion relation a generating function of the partition function satisfies. The main goal being analysing some asymptotic properties of this generating function. We then discuss the relationship of this problem to the problem of finding the asymptotic distribution of the maximum of a certain class of correlated random variables as well as how this problem gives rise to measures related to multiplicative cascade measures.
