In graph theory, a circular-arc graph is the intersection graph of a set of arcs on the circle. It has one vertex for each arc in the set, and an edge between every pair of vertices corresponding to arcs that intersect.
Formally, let
be a set of arcs. Then the corresponding circular-arc graph is G = (V, E) where
and
A family of arcs that corresponds to G is called an arc model.
