An extension of the concept of a complete analytic function, obtained on considering all possible elements of an analytic function in the form of generalized power series (Puiseux series)


Here is a complex variable, is an integer and is a natural number. The series converge in the domains and , respectively. An analytic image can be identified with the class of all elements of the form (*) which are obtained from each other by analytic continuation. The analytic image differs from the complete analytic function by the addition of all ramified elements of the form (*) with , which are obtained by analytic continuation of its regular elements with . After the introduction of a suitable topology, the analytic image is converted to the Riemann surface of the given function.
