Simplicial embeddings
WebbLet K be a simplicial complex and let S be a collection of simplices in K.. The closure of S (denoted ) is the smallest simplicial subcomplex of K that contains each simplex in S. is obtained by repeatedly adding to S each face of every simplex in S. The star of S (denoted ) is the union of the stars of each simplex in S.For a single simplex s, the star of s is the … Webbdef discrete_metric_simplicial_set_intersection (simplicial_set, discrete_space, unknown_dist = 1.0, far_dist = 5.0, metric = None, metric_kws = {}, metric_scale = 1.0,): …

WebbThe tion of tightness of a PL-embedding of a triangulated manifold is closely related to its property of being a Hamiltonian subcomplex of some convex polytope. Tightness of a triangulated manifold is a topological condition, roughly meaning that any simplex-wise linear embedding of the triangulation into Euclidean space is as convex as possible .
