Para-exceptional sequences for tame hereditary algebras and McCammond-Sulway lattices
Eric J. Hanson, Nathan Reading
Noncrossing partition posets in a Coxeter group can fail to be lattices when is not finite. When the lattice property fails for of affine type, McCammond and Sulway's c…

Posets for -polynomials in cluster algebras from surfaces
Vincent Pilaud, Nathan Reading, Sibylle Schroll
We prove a simple formula for arbitrary cluster variables in the marked surfaces model. As part of the formula, we associate a labeled poset to each tagged arc, such that the assoc…
