## Abstract:

In 1988, Hickerson proved the celebrated â€śmock theta conjecturesâ€ť in a collection of ten identities from Ramanujanâ€™s â€ślost notebookâ€ť which express certain modular forms as linear combinations of mock theta functions. In the context of Maass forms, these identities arise from the peculiar phenomenon that two different harmonic Maass forms may have the same non-holomorphic parts. Using this perspective, we construct several infinite families of modular forms which are differences of mock theta functions.## References
