• Resumen

  • Let (X,F) be a foliated surface and G a finite group of automorphisms of X that preserves F. We investigate invariant loci for G and obtain upper bounds for its order that depends polynomially on the Chern numbers of X and F. As a consequence, we estimate the order of the automorphism group of some foliations under mild restrictions. We obtain an optimal bound for foliations on the projective plane which is attained by the automorphism groups of the Jouanolou's foliations.
