Partition Identities for Ramanujan's Third Order Mock Theta Functions

William Y. C. Chen, Kathy Q. Ji, and Eric H. Liu

  Abstract:  We find two involutions on partitions that lead to partition identities for Ramanujan's third order mock theta functions φ(-q) and ψ(-q). We also give an involution for Fine's partition identity on the mock theta function f(q). The two classical identities of Ramanujan on third order mock theta functions are consequences of these partition identities. Our combinatorial constructions also apply to Andrews' generalizations of Ramanujan's identities.
