(mathematics)
A function of complex variables which is analytic in its domain of definition save at a finite number of points which are poles.

Meromorphic Function

 

a function that can be represented in the form of a quotient of two entire functions, that is, the quotient of the sums of two everywhere convergent power series. Meromorphic functions include many important functions and classes of functions (rational functions, trigonometric functions, elliptic functions, the gamma function, the zeta function).
