Abstract
Let be a number field, an algebraic automorphic newform on over , an odd prime does not divide the class number of and the level of . We prove that is determined by its -values twisted by Galois characters of certain -extension of . Furthermore, if is totally real or CM, then under some mild assumption on , the compositum of the Hecke field of and the cyclotomic field is generated by the algebraic -values of twisted by Galois characters of certain -extension of .
