The Mordell integral, quantum modular forms, and mock Jacobi forms
It is explained how the Mordell integral ∫ R e πiτ x 2 − 2 πzx cosh ( πx ) dx unifies the mock theta functions, partial (or false) theta functions, and some of Zagier’s quantum modular forms. As an application, we exploit the connections between q -hypergeometric series and mock and partial theta fu...

Summary: | It is explained how the Mordell integral
∫

unifies the mock theta functions, partial (or false) theta functions, and some of Zagier’s quantum modular forms. As an application, we exploit the connections between
q
-hypergeometric series and mock and partial theta functions to obtain finite evaluations of the Mordell integral for rational choices of

and
