Energy measure singularity dichotomy for MMD spaces

Let (X,d,m,E,F)(X,d,m,\mathcal{E},\mathcal{F}) be a MMD space satisfying VD\operatorname{VD}, PI(Ψ)\operatorname{PI}(\Psi) and CS(Ψ)\operatorname{CS}(\Psi). Assume further that (X,d)(X,d) satisfies the chain condition and that

limr0Ψ(r)r2=0.\lim_{r \downarrow 0} \frac{\Psi(r)}{r^{2}}=0.

Energy measure singularity dichotomy. Then Γ(f,f)m\Gamma(f,f) \perp m for all fFf \in \mathcal{F}. The conjecture predicts singularity of every energy measure under the stated structural and scaling assumptions; the supplied text does not indicate whether it has been proved or disproved.
