Comment (by rws):
At the moment this is implemented:
{{{
sage: Lminus4 = dirichlet_series([kronecker(-4,n) for n in range(1,21)]);
Lminus4
1 + -1/(3^s) + 1/(5^s) + -1/(7^s) + 1/(9^s) + -1/(11^s) + 1/(13^s) +
-1/(15^s) + 1/(17^s) + -1/(19^s) + O(21^(-s))
sage: zeta = dirichlet_series([1]*20); zeta
1 + 1/(2^s) + 1/(3^s) + 1/(4^s) + 1/(5^s) + 1/(6^s) + 1/(7^s) + 1/(8^s) +
1/(9^s) + 1/(10^s) + 1/(11^s) + 1/(12^s) + 1/(13^s) + 1/(14^s) + 1/(15^s)
+ 1/(16^s) + 1/(17^s) + 1/(18^s) + 1/(19^s) + 1/(20^s) + O(21^(-s))
sage: zeta * Lminus4^(-1)
1 + 1/(2^s) + 2/(3^s) + 1/(4^s) + 2/(6^s) + 2/(7^s) + 1/(8^s) + 2/(9^s) +
2/(11^s) + 2/(12^s) + 2/(14^s) + 1/(16^s) + 2/(18^s) + 2/(19^s) +
O(21^(-s))
}}}
Please give a concrete example what you like to see!
