Abstract
Period and index of a curve over a -adic local field such that the fundamental group admits a splitting are shown to be powers of . As a consequence, examples of curves over number fields are constructed where having sections is obstructed locally at a -adic place. Hence the section conjecture holds for these curves as there are neither sections nor rational points.
