The indecomposable-real-element conjecture for superunitary regions
Let be a cluster algebra with a good basis , and let be the subset of indecomposable real elements, where an element is real if and indecomposable if every factorization with has an invertible factor. For , write for its associated function. The indecomposable-real-element conjecture. The -superunitary region is the subset of on which for every :
This would imply equality with the ordinary superunitary region whenever the indecomposable real elements are precisely the cluster variables. The supplied text gives no resolution.
