On the Doi-Naganuma lifting associated with imaginary quadratic fields
Similarly to the real quadratic field case by Doi and Naganuma ([3], [9]) there is a lifting from an elliptic modular form to an automorphic form on SL 2 (C ) with respect to an arithmetic discrete subgroup relative to an imaginary quadratic field. This fact is contained in his …
