Resumen:
Many  extensions  of  General  Relativity  are  based  on  considering  metric  and  affine  structures as independent properties of spacetime.  This leads to the possibility of introducing torsion as an independent degree of freedom.  In this article we examine the effects of torsion on the affine Killing vectors of two-dimensional manifolds.  We give a complete description of the Lie algebras of affine Killing vector fields on homogeneous surfaces.  This can be used in the search of non-metrizable surfaces of interest.
