ERRATUM TO 'MASS EQUIDISTRIBUTION FOR AUTOMORPHIC FORMS OF COHOMOLOGICAL TYPE ON GL_2'

摘要

Corollary 3 of [4] is not known unconditionally, as cohomological automorphic forms on GL_2 over an imaginary quadratic field are not known to satisfy the Ramanujan conjecture. We shall briefly describe the reason for this and discuss what information Theorem 1 of [4] does give in the case of imaginary quadratic fields.
