Degree 1
The L-functions of degree 1 are the
Riemann zeta-function
and the
Dirichlet L-functions
. Here
is a primitive Dirichlet character to a modulus
q
which is the level of the L-function.
Back to the start
On to Degree 2
and the Dirichlet L-functions 
. Here 
is a primitive
Dirichlet character to a modulus q which is the level of the L-function.
