(2+1) Spaces from (3+1) Gravity
Abstract
The reduction mechanism from (3+1) to (2+1) gravity is supported on a criterion in which the Weyl tensor components are required to vanish followed by a dimensional reduction. By applying the proposed procedure to the Plebański-Carter[A] solution of the (3+1) gravity the (2+1) BTZ solution is obtained.
