The Curtain Model is Not a Quasi-Isometry Invariant of CAT(0) Spaces
Elliott Vest
Petyt-Spriano-Zalloum recently developed the notion of a \textit{curtain model}, which is a hyperbolic space associated to any CAT(0) space. It plays a similar role for CAT(0) spac…

Curtain Characterization of Sublinearly Morse Geodesics in CAT(0) Spaces
Elliott Vest
We show that the sublinear Morse boundary of every CAT(0) space continuously injects into the Gromov boundary of a hyperbolic space, which was not previously known even for all CAT…
