摘要
In this paper, uniformly rotating relativistic rings are investigated analytically utilizing two different approximations simultaneously: (1) an expansion about the thin-ring limit (the cross-section is small compared with the size of the whole ring) and (2) post-Newtonian expansions. The analytic results for rings are compared with numerical solutions.
