👉 In mathematics, an "intershade" is a type of graph that can be expressed as a union of two or more smaller graphs. These graphs are often used in the study of complex networks and have been proposed as a way to model complex systems with multiple interacting components. The term "intershade" has also been used to describe the concept of a graph where each component is interconnected with other components through an undirected edge, but where there is no directionality between the edges.
