A "comnverse theorem" is an assertion that an L-function is the L-function of an automorphic object.

theorem
Given a cuspidal automorphic representation $\pi$ of a XXXX group $G$ and a finite dimensional representation $\rho$ of the Weil-Deligne group of $G$, one can form the automorphic L-function $L(s,\pi,\rho)$.

A variety is 'modular' if its Hasse-Weil L-function is the same as the standard L-function of some modular form. The key step in proving Fermat's Last Theorem was showing that certain elliptic curves are modular.
some varieties are modular
Say something about Shimura varieties.

A number field is a finite dimensional extension
of the rational numbers.
The Dedekind zeta function is defined as a
product over the prime ideals of the number
field.
An Artin representation is a finite dimensional
representation of the Galois group of a number
field.
Associated to a number field is a Galois group:
the Galois group of its Galois closure
Associated to any number field is a Galois group: the Galois group of its Galois closure
The local factors of the Artin L-function are constructed from the trace of Frobenius.
