摘要：
The rank of an overpartition pair is a generalization of Dyson's rank of a partition. The purpose of this paper is to investigate the role that this statistic plays in the congruence properties of (pp) over bar (n), the number of overpartition pairs of n. Some generating functions and identities involving this rank are also presented.
