%0 Journal Article %T The probability of long cycles in interchange processes %A Gil Alon %A Gady Kozma %J Mathematics %D 2010 %I arXiv %X We examine the number of cycles of length k in a permutation, as a function on the symmetric group. We write it explicitly as a combination of characters of irreducible representations. This allows to study formation of long cycles in the interchange process, including a precise formula for the probability that the permutation is one long cycle at a given time t, and estimates for the cases of shorter cycles. %U http://arxiv.org/abs/1009.3723v3
