摘要
In this paper, we consider a little-studied observable in classical pure AdS$_3$ gravity: the twist along a geodesic.The motivation is that the twist only supports on the geodesic and may be a candidate element in the center. We study the properties of the twist and get the following results. First, we get the system's evolution generated by the twist, which exhibits a relative shift along the geodesic. Second, we show that the twist commutes with the length of the same geodesic, which supports the proposal that the twist is a candidate element in the center.
