Manning–Wang dimension conjecture for Bowditch boundaries

Let $(G,\mathcal{P})$ be a type $F$ relatively hyperbolic group pair, with Bowditch boundary $\partial(G,\mathcal{P})$, and let $\operatorname{cd}(G,\mathcal{P})$ denote the cohomological dimension of the pair. Manning–Wang dimension conjecture.

$$\dim\partial(G,\mathcal{P})=\operatorname{cd}(G,\mathcal{P})-1.$$

This conjecture relates the topological dimension of the Bowditch boundary to the cohomological dimension of the relatively hyperbolic group pair. The source attributes it to Manning and Wang; its resolution is not established by the supplied text.
