Distributional Torsion of Cosmic Walls crossed by Cosmic Strings

Abstract

Distributional sources of cosmic walls crossed by cosmic strings from Riemann-Cartan (RC) Geometry. The matter density of the planar wall is maximum at the point where the cosmic string crosses the cosmic wall. Cartan torsion is has a support on the cosmic string given by the Dirac $\delta$-function. Off the sources are left with a torsionless vacuum.
