Abstract

From two-line matrix interpretations of Mock Theta Functions ρ(q), σ(q) and ν(q) introduced in [5], we have obtained identities for the partitions generated by their respective general terms, whose proofs are done in a completely combinatorial way. We have also obtained relations between partitions into two colours generated by ρ(q) and σ(q), and also by ν(q).
