An automorphic function of a complex variable
is one which is analytic (except for poles) in a domain
and which is invariant under a countably infinite
group of linear fractional transformations
(also known as Möbius transformations)
Automorphic functions are generalizations of trigonometric
functions and elliptic functions.
