Triangulations of polygons and stacked simplicial complexes: separating their Stanley-Reisner ideals
Gunnar Fløystad, Milo Orlich
A triangulation of a polygon has an associated Stanley-Reisner ideal. We obtain a full algebraic and combinatorial understanding of these ideals, and describe their separated model…

Shift modules, strongly stable ideals, and their dualities
Gunnar Fløystad
We enrich the setting of strongly stable ideals (SSI): We introduce shift modules, a module category encompassing SSI's. The recently introduced duality on SSI's is given an effect…

Profunctors between posets and Alexander duality
Gunnar Fløystad
We consider profunctors $f : P \promap Q$ between posets and introduce their {\em graph} and {\em ascent}. The profunctors $\Pro(P,Q)$ form themselves a poset, and we consider a pa…
