Abstract
A cosmic string described by an interaction Lagrangian and including a U(1) gauge vector field, minimally coupled to a scalar field was considered. This Lagrangian includes also a gravitation interacting scalar term. The field equations have been obtained from the above Lagrangian, these equations were coupled to Einstein`s equations. Such a system of equations has been solved numerically and polynomial expansions derived for the fields which describe the string. With the above solutions the second order corrections to the angular deficit, produced by the string was determined. (author).
