##### In thesis

In this paper we study the geometric location of periodic points of power series defined over fields of prime characteristic *p*. More specifically, we find a lower bound for the absolute value of all periodic points in the open unit disk of minimal period p^{n} of 2-ramified power series. We prove that this bound is optimal for a large class of power series. Our main technical result is a computation of the first significant terms of the pnth iterate of 2-ramified power series. As a by-product we obtain a self-contained proof of the characterization of 2-ramified power series.
