We consider scattering of elastic waves on parallel wedge dislocations in the geometric theory of defects or, equivalently, scattering of point particles and light rays on cosmic strings. Dislocations are described as torsion singularities located on parallel lines, and trajectories of phonons are a

The relation between the R-and P-matrix approaches and the harmonic oscillator representation of the quantum scattering theory (J-matrix method) is discussed. We construct a discrete analogue of the P-matrix that is shown to be equivalent to the usual P-matrix in the quasiclassical limit. A definiti
The topological approach of Ran Λada and Trueba, the general relativistic approach of Sachs, and the O(3) electrodynamics are interlinked and shown to be based on the concept of Faraday's lines of force. In the review by Ran Λada and Trueba [1], electric and magnetic lines of force were discussed a
