Notes:
A homotopy classification scheme is developed for Lorentz metrics that are defined on (2+1)-dimensional space-times of various topologies. The "kink number,'' in the sense of the Finkelstein–Misner kink number in higher dimensions, is discussed, and examples are presented of kink metrics that satisfy the Einstein field equations in 2+1 dimensions.
