Universal mock theta functions and two-variable Hecke-Rogers identities (1402.1884v1)
Published 8 Feb 2014 in math.NT and math.CO
Abstract: We obtain two-variable Hecke-Rogers identities for three universal mock theta functions. This implies that many of Ramanujan's mock theta functions, including all the third order functions, have a Hecke-Rogers-type double sum representation. We find new generating function identities for the Dyson rank function, the overpartition rank function, the M2-rank function and related spt-crank functions. Results are proved using the theory of basic hypergeometric functions.
