Non-cuspidal Bianchi modular forms and Katz p-adic L-functions
摘要
Let K be an imaginary quadratic field. In this article, we construct p-adic L-functions of non-cuspidal Bianchi modular forms by introducing the notions of C-cuspidality and partial Bianchi modular symbols. When p splits in K, we focus on p-adic L-functions of non-cuspidal base change Bianchi modular forms, showing that they factor as products of two Katz p-adic L-functions.
