An exact solution for 2+1 dimensional critical collapse
arXiv:gr-qc/0008023 · doi:10.1103/PhysRevD.63.044007
Abstract
We find an exact solution in closed form for the critical collapse of a scalar field with cosmological constant in 2+1 dimensions. This solution agrees with the numerical simulation done by Pretorius and Choptuik of this system.
