A Probabilistic Proof of the Rogers Ramanujan Identities
The asymptotic probability theory of conjugacy classes of the finite general
linear and unitary groups leads to a probability measure on the set of all
partitions of natural numbers. A simple method of understanding these measures
in terms of Markov chains is given and compared with work on the uniform
measure. Elementary probabilistic proofs of the Rogers-Ramanujan identities
follow. As a corollary, the main case of Bailey's lemma is interpreted as
finding eigenvectors of the transition matrix of the Markov chain. It is shown
that the viewpoint of Markov chains extends to quivers.Comment: Final version, to appear in Bull LMS. The one math change is to fix a
typo in the limit in Corollary 2. We also make two historical correction
