Minkowski decompositions for generalized associahedra of acyclic type
Dennis Jahn, Robert Löwe, Christian Stump
We give an explicit subword complex description of the generators of the type cone of the g-vector fan of a finite type cluster algebra with acyclic initial seed. This yields in pa…

On Moduli Spaces of Convex Projective Structures on Surfaces: Outitude and Cell-Decomposition in Fock-Goncharov Coordinates
Robert Haraway, Robert Löwe, Dominic Tate +1
Generalising a seminal result of Epstein and Penner for cusped hyperbolic manifolds, Cooper and Long showed that each decorated strictly convex projective cusped manifold has a can…
