Automorphic Function
An automorphic function 
of a Complex variable 
is one which is analytic (except forPoles) in a domain 
and which is invariant under a Denumerably Infinite group of LinearFractional Transformations (also known as Möbius Transformations)
Automorphic functions are generalizations of Trigonometric Functions and Elliptic Functions.See also Modular Function, Möbius Transformations, Zeta Fuchsian
