Approximate projective homogeneity conjecture for the pseudo-circle

About 10 years old · traced to

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:C→Yf,g:C\to Y be surjections with

deg⁡(f)=deg⁡(g).\deg(f)=\deg(g).

A local homeomorphism φ:C→C\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 x∈Cx\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.
