A simplicial complex is a family of finite vertex sets closed under taking subsets.
A simplicial complex is a mathematical structure used in algebraic topology and combinatorial mathematics to study spaces and their properties. It is a way of building up a geometric object from simpler building blocks called simplices. ### Definition of a Simplicial Complex A simplicial complex \( K \) is a set of simplices that satisfies two conditions: 1. **Non-emptiness**: The empty set is in \( K \).
