Título: The space of relative orders

Resumen:  We introduce the space of relatives orders on a group and show that it is compact whenever the group is finitely generated. We use this to give a generalization of Morris' theorem stating that a (non-trivial) finitely generated and amenable subgroup of Homeo+(ℝ) has an infinite cyclic quotient. This is a joint work with Cristobal Rivas.
