Morse subsets of CAT(0) spaces are strongly contracting
Published 4 Oct 2018 in math.GR | (1810.02119v1)
Abstract: We prove that Morse subsets of CAT(0) spaces are strongly contracting. This generalizes and simplifies a result of Sultan, who proved it for Morse quasi-geodesics. Our proof goes through the recurrence characterization of Morse subsets.
