报告摘要：Mock theta functions were first introduced by Ramanujan in his last letter to Hardy. Historically, mock theta functions can be represented by Eulerian forms, Hecke-type double sums, Appell-Lerch sums, and Fourier coefficients of meromorphicJocobi forms. In this talk, we mainly focus on Hecke-type double sums. Especially, with the aid of some q-series identities, we establish the Hecke-type double sums for some new mock theta functions.
