An **acyclic space** can refer to several concepts depending on the context, but it is most commonly associated with graph theory and algebraic topology. 1. **In Graph Theory**: An acyclic graph (or directed acyclic graph, DAG) is a graph with no cycles, meaning there is no way to start at any vertex and follow a sequence of edges to return to that same vertex.
