    Definitions: Holomorphic and Meromorphic

    • A function that is analytic on a region \(A\) is called holomorphic on \(A\).
    • A function that is analytic on \(A\) except for a set of poles of finite order is called meromorphic on \(A\).

    Example \(\PageIndex{1}\)

    Let

    \[f(z) = \dfrac{z + z^2 + z^3}{(z - 2)(z - 3)(z - 4)(z - 5)}. \nonumber \]

    This is meromorphic on \(C\) with (simple) poles at \(z = 2, 3, 4, 5.\)
