Characterizing intersection classes of g
✍ Edward R. Scheinerman 📂 Article 📅 1985 🏛 Elsevier Science 🌐 English ⚖ 571 KB

A graph is an intersection graph if it is possible to assign sets to its vertices so that adjacency corresponds exactly to nonempty intersection. If the sets assigned to vertices must belong to a pre-specified family, the resulting class of all possible intersection graphs is called an intersection

Let µ be an eigenvalue of the graph G with multiplicity k. A star complement for µ in G is an induced subgraph H = G -X such that |X| = k and µ is not an eigenvalue of G -X. Various graphs related to (generalized) line graphs or their complements are characterized by star complements corresponding t
