This paper is an advanced survey of the modern analytic theory of \(L\)-functions. It begins with a discussion of general \(L\)-functions generated by the Langlands philosophy, and then goes on to review the major conjectures about them. This is followed by a description of function field analogues, Dirichlet \(L\)-functions, special values, subconvexity and resulting equidistribution results, \(\text{GL}(2)\) tools, and finally, symmetry and attacks on the Generalized Riemann Hypothesis.
One of the main messages of the paper is that one should try in general to work with families of \(L\)-functions, rather than individual ones. This point is well illustrated by the description of the “amplification method”, which produces bounds for individual \(L\)-functions by averaging over an appropriate family.
