The lecture covers the graph minor theory based on the results of Robertson and Seymour, with the emphasis on the new trends in this area. The knowledge of the results covered by NDMI059 or NDMI073 is assumed.

Course completion requirements -

Passing grade for tutorials (zápočet) is obtained on the basis of active participation, especially discussions of the solutions of the homework problems assigned during the lectures and presentations of studied papers; in exceptional cases, individual consultations can be used instead. The nature of these requirements precludes retakes. Passing grade for tutorials is required before taking the exam, this can be relaxed at the discretion of the lecturer in exceptional cases (early exam dates).

Requirements to the exam -

Oral exam consisting of 2-3 questions regarding general overview of topics covered by the lectures and a more detailed discussion of one of the topics, assigned in advance.

Syllabus -

Properties of graphs on surfaces, tree decompositions and the structure of the graphs without a forbidden minor, well-quasiordering by the minor relation, testing of existence of disjoint paths and of minors, the structure of t-connected graphs without K_t and the connection to Hadwiger conjecture.
