Well-balanced classes are asymptotically negligible for repetitive finite-local-complexity tilings

At least 7 years old · documented by

Let T{\bf T} be a tiling that is repetitive and has finite local complexity, and let ΩT\Omega_{\bf T} be its continuous hull. Consider the top-degree real cohomology group Hn(ΩT,R)H^n(\Omega_{\bf T},\mathbb R), where nn is the dimension of the tiling. A cohomology class is well-balanced if it has the corresponding bounded mass-transport property, and it is asymptotically negligible if it has the corresponding weakly pattern-equivariant transport property.

Well-balanced-class conjecture. Every well-balanced class in

Hn(ΩT,R)H^n(\Omega_{\bf T},\mathbb R)

is asymptotically negligible.

The claim would identify the two cohomological conditions governing bounded and weakly pattern-equivariant mass transport for every repetitive tiling with finite local complexity. The supplied text does not state whether this conjecture has been proved or disproved.
