Abstract:Let A be a set of positive integers with gcd (A) = 1, and let p A (n) be the partition function of A. Let c 0 = pgrradic2/3. If A has lower asymptotic density agr and upper asymptotic density beta, then lim inf log p A (n)/c 0 radicn gE radicagr and lim sup log p A (n)/c 0 radicn lE radicbeta. In particular, if A has asymptotic density agr > 0, then log p A (n) sim c0radicagrn. Conversely, if agr > 0 and log p A (n) sim c 0 radicagrn, then the set A has asymptotic density agr.
