Final Exam scheduled for Wednesday Dec 16 at 8:30 pm for 3 hours. Room MATH 103. I will be available for questions Monday 1-3 and Tuesday 11-12 and 1-3. Perhaps other times as well. The exam will probably consist of 10 questions of equal credit. I will be selcting 4-5 problems from the posted 25 problems and perhaps stealing some ideas from assignments. Then the remaining 4-5 questions for the final will be new.

This is an Honours course that has substantial use of proofs. The subject of Graph Theory can often be conveyed through pictures and students (and myself) find this makes the subject more appealing.
Everyone has been up at the blackboard once and you all seemed pretty comfortable. We will have had problem presentations (for grading) on Wednesday Oct 14, Friday Oct 16 and Wednesday Oct 21 from the first 9 problems. My intention is to give you a sheet for the problems we are looking at and ask you to indicate whether you are ready to present, somewhat ready or not ready. Then I will select some presenters from those who say they are ready. Some portion of your grade comes from the sheet and some from the presentation. The presentation in the best case will be complete and clear and well delivered. Grading for me is a bit murky at this point but these three categories initially spring to mind. I will endeavour that everyone presents at least 2, perhaps 3 problems by the end of the course. The grade for this will replace a midterm.
  • problems 1-4.for classroom presentations.  
  • problems 5-9.for classroom presentations.  
  • problems 10-15.for classroom presentations.  
  • problems 16-20.for classroom presentations.  
  • problems 21-25.for classroom presentations.  


  • Our one and only midterm is now scheduled for Monday Oct 26.

    The text by Doug West should be readily accessible. Other texts would also be suitable. The book by Reinhard Diestel is an excellent overview at a slightly higher level than the book by West. Free download at Diestel website
    Any notes I type may look authoritative when typed so be wary. They may look perfect but may still contain errors! I don't have an editor.
    I arrive most days by 9:00 but will be teaching MATH 223 at 9 MWF. I typically do not read my email from home (i.e. evenings and weekends).
