Definition: "Coincident" is a term used in mathematics, specifically in the field of combinatorics and graph theory. It refers to two or more events that occur at the same time or are related by some mechanism. In the context of a simple graph with n vertices (or nodes), "coincident" can be defined as follows: - A set S of edges is said to be "coincident" if it contains exactly one edge from each vertex in V(S). For example, consider a
