Abstract
Let k be a positive integer and m be an integer. Garvan’s k-rank \(N_k(n,m)\) is the number of partitions of n into at least \((k-1)\) successive Durfee squares with k-rank equal to m. In this paper we give some asymptotics for \(N_k(n,m)\) with \(|m|\ge \sqrt{n}\) as \(n\rightarrow \infty .\) As a corollary, we give a more complete answer for the Dyson’s crank distribution conjecture. We also establish some asymptotic formulas for finite differences of \(N_k(n,m)\) with respect to m with \(m\gg \sqrt{n}\log n.\)
