👉 In mathematics, an antigraph is a graph that represents a set of edges where each edge connects two vertices in such a way that no vertex has more than one edge connected to it. In other words, an antigraph is defined as a directed graph where every vertex has at most one outgoing edge and every vertex has at most one incoming edge. Antigraphs are often used in the context of graph theory to model networks with multiple edges between different vertices, which can be useful for studying network properties
