New fifth and seventh order mock theta function identities
arXiv:1907.04803
Abstract
We give simple proofs of Hecke-Rogers indefinite binary theta series identities for the two Ramanujan fifth order mock theta functions $Ï_0(q)$ and $Ï_1(q)$ 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.
