Colliding plane waves in \(N=1\) classical supergravity. (English) Zbl 1222.83188

Summary: An exact solution is presented for colliding plane waves in \(N=1\) classical supergravity. Contrary to the situation in ordinary gravity, this solution is nonsingular everywhere. The Grassmann algebra is shown to be responsible for the vanishing of terms in the Raychaudhuri equation that generate the singularity in the pure gravity case.
