Annotation -
Introduction to combinatorics and graph theory. We lay stress on active knowledge of basic definitions and methods (relation, mapping, graph, exact formulation of mathematical theorems, problem solving and proofs of simple statements).

Course completion requirements -

For credit you need to get 100 points out of at least 150 possible continuously awarded for tests, homework and other activities.

The ongoing nature of the inspection does not imply a right to request corrective tests nor alternative homework assignments.

In justified cases (long-term illness, stay abroad, etc.) the lecturer may set individual conditions for credit granting.

Credit is a condition for taking the exam.

The exam can be written, oral or combined. The exam may be arranged in contact or distant form.

The exam format is decided by the educator(s).

Result of tests accomplished during the teaching period may be taken into account at the exam.

Requirements to the exam -

The requirements for the exam correspond to the syllabus of the subject to the extent that it was covered in lectures, tutorials and self-study.

The ability to apply the acquired knowledge in problem solving is also required.

Credit is a condition for taking the exam.

Syllabus -

Notation, motivating problems, the concept of a proof, proof by induction.

Combinatorics:

  • Relation: mapping (function, permutation), equivalence.
  • Partial ordering: chains and antichains, large implies tall or wide.
  • Combinatorial counting: the number of subsets, of subsets of size k, of all mappings, of all injective mappings, of permutations.
  • The binomial theorem. Estimates the factorial function and binomial coefficients.
  • Inclusion-exclusion formula, applications (hatcheck lady).

Probability:

  • Probability space (at most countable, all subsets are events).
  • Independent events, conditional probability.
  • Random variable: distribution function, expectation, linearity, most common distributions.

Graph theory:

  • Elementary notions: complete graph, complete bipartite graph, path, cycle, vertex degree, subgraph, isomorphism.
  • Handshaking lemma.
  • Eulerian graphs: trail, walk, characterisation, including directed case, strong and weak connectivity.
  • Trees: various characterisations, existence of a leaf.
  • Planar graphs: Euler's formula, maximum number of edges.
  • Graph coloring: characterisation of bipartite graphs, d-degenerate graphs, 5-color theorem for planar graphs (Kempe's chains).

Optional topics:

  • Erdős-Szekeres lemma on monotone subsequences.
  • Probabilistic proofs (e.g. existence of a 3-paradoxical tournament).
  • Graph score.
  • Platonic solids.
  • Sperner's lemma, application on the HEX game.
