Abstract: We will define an L-series for harmonic Maass forms and prove their functional equations. A converse theorem for these L-series will be discussed and, as an application, we will give a summation formula for harmonic lifts of cusp form. This is joint work with M. Lee, W. Raji and L. Rolen.
