Abstract

Abstract An approximate solution of Einstein-Cartan field equation describing a topological global monopole is presented. The gravitational field of the torsionic monopole is shown to be attractive. The deficit angle is shown to receive a contribution of torsion which is well within experimental limits in agreement with COBE data. This provides a mechanism for an indirect evidence for Cartan torsion. The presence of torsion may also lead to a stable configuration of the global monopole after inflation as happens in Brans-Dicke gravity.
