Graph homology is a concept in algebraic topology that extends the ideas of homology from topological spaces to combinatorial structures known as graphs. Essentially, it assigns algebraic invariants to graphs that capture their topological properties, allowing one to study and classify graphs in a way that is analogous to how homology groups classify topological spaces. ### Key Elements of Graph Homology 1. **Graphs**: A graph consists of vertices and edges connecting pairs of vertices.
