Simplicial Complex

Definition

A simplicial complex is a mathematical construction from algebraic topology that represents topological spaces by assembling simple geometric building blocks. These blocks include points, line segments, triangles, and their higher-dimensional analogues, known as simplices. These components are joined together along their faces in a specific manner. This structure provides a discrete and combinatorial way to study the shape and connectivity of complex data or abstract spaces. It serves as a fundamental tool in computational topology.
