Approximate projective homogeneity conjecture for the pseudo-circle

Let CC be a pseudo-circle and YY a planar circle-like continuum. For maps between circle-like continua, write deg(f)\deg(f) for the integer induced by ff on first Čech cohomology. Let f,g:CYf,g:C\to Y be surjections with

deg(f)=deg(g).\deg(f)=\deg(g).

A local homeomorphism φ:CC\varphi:C\to C is a map that is locally a homeomorphism at every point.

Pseudo-circle projective-homogeneity conjecture. For every ϵ>0\epsilon>0, there exists a local homeomorphism φ\varphi of CC onto itself such that, for every xCx\in C,

f(x)g(φ(x))<ϵ.|f(x)-g(\varphi(x))|<\epsilon.

The conjecture asks for approximate projective homogeneity of the pseudo-circle under the degree condition. The source states it after noting that the pseudo-circle lacks the corresponding property in the setting previously considered; no resolution is supplied here.
