New singular and nonsingular colliding wave solutions in Einstein-Maxwell-Scalar theory.
A technique is given to generate coupled scalar field solutions in colliding Einstein-Maxwell (EM) waves. By employing the Bell - Szekeres solution as seed and depending on the chosen scalar field, it is possible to ...
Cosmic strings coupled with a massless scalar field
A scalar field generalization of Xanthopoulos’s cylindrically symmetric solutions of the vacuum Einstein equations is obtained. The obtained solution preserves the properties of the Xanthopoulos solution, which are regular ...
