Simplicial complex connectivity
WebbGiven a simplicial complex δ on vertices {1, …,n} and a fieldF we consider the subvariety of projective (n−1)-space overF consisting of points whose homogeneous coordinates have support in δ. We give a simple rational expression for the zeta function of this singular projective variety overF q and show a close connection with the Betti numbers of the … WebbIn this paper we develop a complete theory of connectivity for simplicial complexes, and a related theory for graphs. The theory takes the form of a bigraded family of groups Aqn …
