Questions in Graph Theory:

In the subject of the degree sequence of graph, answer the following:

  • When does a d-regular graph have an Eulerian trail? and When does it have an Eulerian circuit? Note: a d-regular graph is one with degree sequence (d, d, d, . . . , d) for example.
  • Can a tree be a regular graph? Why or why not
