The course will be concerned with topics in classical and modern graph theory:
- Properties of trees, cycles, matching, factors
- Forbidden subgraphs
- Planar graphs
- Graph colorings
- Random graphs
- Ramsey theory
- Graph minors
The class is oriented towards problem solving. The goal of the course for the students is to gain knowledge about the fundamental concepts in graph theory, solve interesting problems, learn how to write and present the proofs creatively.
Basic knowledge of linear algebra; appropriate for students starting from 5th semester.
Please register for the homework on this website.
A problem sheet will be published here every Wednesday (starting on October 18) with 4 problems for 5 points each. Due date is Wednesday the following week at 9:45 am.
Rules of submission:
- In each paper that you submit, you shall leave a right margin of width at least 1/3 of the paper so that the tutors have enough space to write their comments.
- The submitted pages must be stapled together and your name has to be written on the front page with capital letters.
- The problems are solved and solutions are submitted by individual students or pairs of students.
- Every submission shall contain the solution to at most three problems.
- When submitting in pairs, each student shall write at least one solution.
- You can write your solutions either in English (preferable) or in German.
- You shall submit your solutions in a blue box labeled "Graph Theory" in the atrium of the math building (20.30).
There is the possibility to obtain a bonus by successfully working the exercise sheets.
In order to receive the bonus you need to obtain at least half of the total amount of points on the first 6 sheets, as well as on the second 6 sheets.
The bonus will improve the grade of a passed exam of this lecture at the end of the semester by one step (0.3 or 0.4).
The main source is the book Graph Theory by Reinhard Diestel. The English edition can be read for free on the author’s web site (http://diestel-graph-theory.com/).
