Mini Course: "Edge colouring of multigraphs and the Tashkinov trees method"

Schedule: Introduction: Mon Oct 25 14:15-15:15 Lecture 1:      Tues Oct 26 14:15-15:45 - Room 025/026* Lecture 2:      Thurs Oct 28 8:30-10:00 - Room 032* Lecture 3:      Thurs Oct 28 10:30-12:00 - Room 025/026* Lecture 4:      Fri Oct 29 10:15-11:45 - Room 007/008*. Program: In this course we will study edge colouring in multigraphs, with an emphasis on the method of Tashkinov trees . A sophisticated generalization of the method of alternating paths, this technique was introduced by Tashkinov to address questions such as the Goldberg-Seymour problem. In particular we will see the theorem of Tashkinov that forms the foundation of the method, and how to apply it to obtain some of the many important results for multigraph edge colouring for which it has been used. Moreover, these applications typically come with efficient algorithms, since the proof of Tashkinov's Theorem is algorithmic. All are welcome to attend. No prior knowledge of edge colouring will be assumed. Detailed description of the program . *Lectures from Tuesday to Friday will take place at: Arnimalle 6. If you are planning to participate, please send a note to: i.brunke@fu-berlin.de .

Berlin-Poznań-Hamburg Seminar on Combinatorics and Algorithms

This seminar was started by Prof. Michał Karoński from the Adam Mickiewicz University in Poznań and by Prof. Hans Jürgen Prömel (at the time) from Humboldt University of Berlin in the mid 1990's. The event alternates between Berlin, Poznań and (more recently) Hamburg, covering a wide variety of topics in extremal and probabilistic combinatorics, algorithmic discrete mathematics, as well as related fields. This year it takes place on June 8 and 9 at the Free University of Berlin.

Location: Freie Universität Berlin Institut für Mathematik Arnimallee 3 (Room 001) 14195 Berlin
