An orthoset is a set equipped with a symmetric, irreflexive binary relation. With any (anisotropic) Hermitian space H, we may associate the orthoset ( P ( H ) , ⊥ ) , consisting of the set of one-dimensional subspaces of H and the us...

Given a locally finite set X ⊆ R d and an integer k ≥ 0 , we consider the function w k : Del k ( X ) → R on the dual of the order-k Voronoi tessellation, whose sublevel sets generalize the notion of alpha shapes fro...
