Colliding wave solutions in 2 + 1-dimensions
Abstract
Abstract We identified a new metric that describes both colliding electromagnetic shock waves and scalar waves without cosmological constant in 2 + 1-dimensions. To the future of collision point our metric has spacelike singularity so that the electromagnetic solution differs from its 3 + 1-dimensional counterpart. Our interaction region with scalar waves is related through the Kaluza–Klein argument with the 3 + 1-dimensional Schwarzschild spacetime.
