Combinatorics |
an upper-level introductory course in enumeration, graph theory, and design theory |
by Joy Morris |
This free undergraduate text book provides an introduction to enumeration, graph theory, and design theory. It is aimed
at upper-level undergraduate students and the exercises expect some mathematical sophistication, including a reasonable
ability to construct proofs.
The text is designed to be used in an undergraduate course, but could be suitable for independent study by a student with
some mathematical background and understanding of proofs. It does not assume any background knowledge of combinatorics.
The book is being released online with a Creative Commons license (Attribution-NonCommercial-ShareAlike 2.0).
It has already been used as a textbook for several semesters by 2 different instructors
at the University of Lethbridge, as well as at a number of other universities. Version 2.1 (July 2022) includes the updates of 2.0
(several optional new sections, a web-based format, an appendix on complex numbers and an appendix containing biographies of
mathematicians whose work is referenced) as well as some additional biographies and other edits.
