Course objectives
The aim of this advanced subject is to introduce students to the basic and selected advanced concepts of matroid theory and its connections to combinatorial optimization. Roughly saying, matroids present an algebraic/geometric generalization of graphs, and everybody should know their connection with the greedy algorithm. However, matroid theory includes much more interesting topic and this subject touches many of them, including some cutting edge development in the recent years. At the end, students should: understand basic principles of matroid theory including applications in optimization; and be able to continue with some scientific work in this area if they choose to.
Syllabus
  • What is a matroid, relations to graphs and to linear algebra.
  • Matroid representations, finite fields. Duality and minors.
  • Matroids and the greedy algorithm.
  • Totally unimodular matrices and regular matroids. Seymour's decomposition.
  • Matroids and polyhedra, matroid intersection, Edmond's algorithm.
  • Excluded minors for matroid representability, Rota's conjecture.
  • Towards "matroid minor theory".

Teaching methods
This is an advanced theoretical course, taught in English, and conducted quite informally (a seminar-type lecturing). Students are expected to actively participate in all the lectures and tutorials.
Assessment methods
Evaluation is based on a mandatory written individual homework assignment (one essay), and on a subsequent oral exam.
Language of instruction
English
Follow-Up Courses
Further comments (probably available only in Czech)
Study Materials
The course is taught once in two years.
