Math 443 Section 101
Online Course Material 


  • Notations. I will print up and give you a copy for midterm.  
  • Topics covered up to midterm. at least an outline of the major ideas. I seem to be missing a card trick. 
  • Course Outline: grading scheme etc. 

  • 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.
    I will devote about 1/3 of the class time to student presentations of solutions to 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 will be caring. I will endeavour that everyone presents at least 2 problems by the end of the course.

  • Problems 1-4: for presentation Friday Jan 12. 
  • Problems 5-9: for presentation Monday Jan 22 (also problem 4 from previous set). 
  • Assignment 1 Due Friday Jan 26 

  • Various texts would be useful. The book by Reinhard Diestel is an excellent overview at a slightly higher level than some. The UBC library gives you access to this Springer text in electronic form. Also Diestel website
    The text by Doug West is readily accessible. 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 or so. I will be teaching MATH 340 from 12-1 MWF. I typically do not read my email from home (i.e. evenings and weekends).

    Graphs appear in many applications. Often unexpectedly. Some notes on the problem of squared rectangles. The interesting outcome of this is searching for squared rectangles of n squares con be done by generating all (planar) graphs with n edges.

  • De Bruijn Card Trick   Great for students of a variety of ages. But can you do bit calculations in your head?
