    en.wikipedia.org/wiki/Zeros_and_poles

    A zero of a meromorphic function f is a complex number z such that f(z) = 0. A pole of f is a zero of 1/ f . If f is a function that is meromorphic in a neighbourhood of a point z 0 {\displaystyle z_{0}} of the complex plane , then there exists an integer n such that
