Special Values
- A vertex with degree 0 is called an isolated vertex.
- A vertex with degree 1 is called a leaf vertex or end vertex, and the edge incident with that vertex is called a pendant edge. In the graph on the right, {3,5} is a pendant edge. This terminology is common in the study of trees in graph theory and especially trees as data structures.
- A vertex with degree n-1 in a graph on n vertices is called a dominating vertex.

Famous quotes containing the words special and/or values:
“We agree fully that the mother and unborn child demand special consideration. But so does the soldier and the man maimed in industry. Industrial conditions that are suitable for a stalwart, young, unmarried woman are certainly not equally suitable to the pregnant woman or the mother of young children. Yet “welfare” laws apply to all women alike. Such blanket legislation is as absurd as fixing industrial conditions for men on a basis of their all being wounded soldiers would be.”
—National Woman’s Party, quoted in Everyone Was Brave. As, ch. 8, by William L. O’Neill (1969)
“Postmodernity is the simultaneity of the destruction of earlier values and their reconstruction. It is renovation within ruination.”
—Jean Baudrillard (b. 1929)
