Q: number-theoretic congruences with geometry and topology?

john mangualThere are many examples of q-series identities being proven by interpreting them as generating series of geometric invariants like the Donaldson invariants. I would like to know if there are ways of establishing congruences among the coefficients of theta functions or other q-series using geomet...

@john what is that second link? If I try to use tricks I know to get the actual arXiv link, I get arxiv.org/abs/math/0309208, which is probably wrong. — David Roberts 17 hours ago
@john this might be it: arxiv.org/abs/math/0309108, but I'd need you to confirm. (For reference, the first link should probably be replaced by arxiv.org/abs/0808.1442) — David Roberts 16 hours ago
