For some full measure subset B of the set of iet's (i.e. interval exchange
transformations) the following is satisfied: Let X be a Cr, 1β€rβ€β, vector field, with finitely many singularities, on a compact
orientable surface M. Given a nontrivial recurrent point pβM of X, the
holonomy map around p is semi-conjugate to an iet E:[0,1)β[0,1). If
EβB then there exists a Cr vector field Y, arbitrarily close to X, in
the Crβtopology, such that Y has a closed trajectory passing through p.Comment: 7 pages, 1 figur
