We describe the structure of the set of periodic points in dimension 2. As a consequence we show that given a local biholomorphism F , in dimension 2 with finite orbits, there exists an analytic curve passing through the origin and contained in the fixed point set of some non-trivial iterate of F. As an application we obtain that at least one eigenvalue of the linear part of F at the origin is a root of unity. Moreover, we show that such a result is sharp by exhibiting examples of local biholomorphisms, with finite orbits, such that exactly one of the eigenvalues is a root of unity. These examples are subtle since we show they can not be embedded in one parameter groups.
