Strict contractions and exotic so 0 (d, 1) quotients:

Grant S. Lakeland, Christopher J. Leininger

Research output: Contribution to journalArticlepeer-review


For d≤4, we describe an elementary construction of nonzero degree, strict contractions between closed, oriented hyperbolic d-orbifolds. Appealing to work of Guéritaud-Kassel and Tholozan, these examples determine exotic quotients of SO0(d,1).
