Chudnovsky-Ramanujan type formulae for non-compact arithmetic triangle groups
This paper extends ideas from prior work to derive a complete list of Chudnovsky-Ramanujan type formulae for \(1/\pi\) associated with modular curves corresponding to non-compact arithmetic triangle groups. A number of new series expansions are derived not appearing in prior literature. The paper also provides an algorithm to rigorously compute the singular values of normalized Eisenstein series of weight 2.
