Query: Geodesics around line defects in elastic solids   Topological defects in solids, usually described by complicated boundary
conditions in elastic theory, may be described more simply as sources of a
gravity- like deformation field in the geometric approach of Katanaev and
Volovich. This way, the deformation field is described by non-Euclidean metric
that incorporates the boundary imposed by the defects. A possible way of
gaining some insight into the motion of particles in a medium with topological
defects (e.g., electrons in a dislocated metal) is to look at the geodesics of
the medium around the defect. In this work, we find the exact solution for the
geodesic equation for elastic medium with a generic line defect, the
dispiration, that can either be a screw dislocation or a wedge disclination for
particular choices of its parameters.
