New fifth and seventh order mock theta function identities

Number Theory 2019-07-11 v1 Combinatorics

Abstract

We give simple proofs of Hecke-Rogers indefinite binary theta series identities for the two Ramanujan fifth order mock theta functions χ0(q)\chi_0(q) and χ1(q)\chi_1(q) and all three of Ramanujan's seventh order mock theta functions. We find that the coefficients of the three mock theta functions of order 7 are surprisingly related.
