Yousef Alavi Memorial Symposium
Western Michigan University
One of Yousef Alavi's interesting contributions to graph theory was the topic of double vertex graphs about twenty years ago. Independently, and about the same time, Bagga, Varma, and I began our investigations into a similar concept, the super line graph of index 2. In this talk we survey the two topics, comparing similarities and differences.
