Scalar self-interaction in the spacetime of a cosmic dispiration

In the present paper we investigate classical self-interaction associated with a charged scalar point particle placed at rest in gravitational field of linear topological defect known literature as cosmic dispiration, combination string screw dislocation. We found exact expressions for Green's function and, consequently, self-energy by considering both massive and massless particles. numerical graphs analyze nature self-interactions dispiration spacetime itself cases pure dislocation spacetimes.
