Uniform quasicircle conjecture for CaTherine wheels

Let R>r>0R>r>0, let GG be a Kleinian group, and let ff be a CaTherine wheel invariant under GG. Assume that the injectivity radius of \bbH3/G\bbH^3/G lies everywhere in the interval [r,R][r,R]. Uniform quasicircle conjecture. There is a finite constant K(r,R)K(r,R), depending only on rr and RR, such that ff is a K(r,R)K(r,R)-CaTherine wheel. This would provide uniform geometric control of CaTherine wheels under a two-sided injectivity-radius bound and may help estimate the conformal dimension of boundaries of hyperbolic groups.
