Comment on ``Perturbative Method to solve fourthorder Gravity Field Equations"
Abstract
We reconsider the cosmic string perturbative solution to the classical fourthorder gravity field equations, obtained in Ref.\cite{CLA94}, and we obtain that static, cylindricaly symmetric gauge cosmic strings, with constant energy density, can contain only $\beta$terms in the first order corrections to the interior gravitational field, while the exact exterior solution is a conical spacetime with deficit angle $D=8\pi\mu$.
