Computing Euler products and coefficients of classical modular forms for twisted L-functions
Pascal Molin
We describe a complete algorithm to compute millions of coefficients of classical modular forms in a few seconds. We also review operations on Euler products and illustrate our met…

Computing groups of Hecke characters
Pascal Molin, Aurel Page
We describe algorithms to represent and compute groups of Hecke characters. We make use of an id{è}lic point of view and obtain the whole family of such characters, including trans…
