Subpolynomial maximal resistance in degree-two fractal mother graphs

Let G(2,m,n)\mathcal G(2,m,n) be the finite fractal mother graph with branching parameter mm and level nn, and let its maximal resistance mean the maximum effective resistance between the relevant vertices of the graph.

Subpolynomial resistance conjecture. The maximal resistance in G(2,m,n)\mathcal G(2,m,n) grows slower than any power of nn:

for every α>0,Rmax(G(2,m,n))=o(nα).\text{for every }\alpha>0,\quad R_{\max}(\mathcal G(2,m,n))=o(n^\alpha).

The authors contrast this with the degree-one case and state that they will prove recurrence of G(2,m,)\mathcal G(2,m,\infty) in future work; the subpolynomial resistance assertion itself remains unproved here.
