Abstract

In this work one shows that given a connected CC^\infty-manifold MM of dimension 2\geq 2 and a finite subgroup G\Diff(M)G\subset \Diff(M), there exists a complete vector field XX on MM such that its automorphism group equals G×RG\times \mathbb{R} where the factor R\mathbb{R} comes from the flow of XX.
