Choi, Youn-Seo

Professor

q-hypergeometric series, Ramanujan's mock theta function

Youn-Seo Choi works on analytic number theory, especially q-series and the subjects related to the Jacobian theta functions. He has tried to understand and prove the results connected to Ramanujan's mock theta functions in Ramanujan's Lost Notebook with the theory based on q-hypergeometric series and the combinatorics. He has also studied the theory of the Jacobian's theta functions which can be applied to extend the understanding of the Jacobian elliptic functions and the related topics.
