Higher level cusp forms on exceptional group of type E7
Higher level cusp forms on exceptional group of type E7
By using new techniques with the degenerate Whittaker functions developed by Ikeda and Yamana, we construct a higher-level cusp form on GE7,3 (exceptional similitude group of type E7), called Ikeda type lift, from any Hecke cusp form whose corresponding automorphic representation has no supercuspidal local components. This generalizes our earlier …
