Abstract: Polynomials and rational maps are considered as dynamical systems on the field Q_p of p-adic numbers. For a polynomial with coefficients in the ring of p-adicintegers, the space is decomposed into minimal components and their attracting basins. A transitive locally expanding polynomial, restricted to its Julia subset, is conjugate to a subshift of finite type. For rational maps, the homographic transformations on the projective line over Q_p are studied. Such a system has countablely many minimal components, when it admits fixed points and has only finitely many minimal components when it has no fixed point.
