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).

  • Basic notation, motivating examples, the concept of a proof, proof by induction.
  • Mappings, relations, equivalences. Permutations.
  • Basic combinatorial counting (the number of subsets, of subsets of size k, of all mappings, of all injective mappings, of permutations). The binomial theorem.
  • Inclusion-exclusion formula, applications (hatcheck lady).
  • Probability space (at most countable, all subsets are events). Independent events, conditional probability. Random variable, distribution function. Expectation, examples of calculation.
  • Basic notions of graph theory, path/circuit/walk, isomorphism, etc.
  • Characterisation of Eulerian graphs (including directed case; strong and weak connectedness).
  • Trees (various characterisations, existence of a leaf).
  • Planar graphs, Euler's formula, maximum number of edges.
  • The chromatic number of a graph, characterisation of bipartite graphs, chromatic number of a d-degenerate graph is at most d+1; 5-colorability of planar graphs (using Kempe's chains).
  • Partial orderings, chains and antichains, large implies tall or wide, Erdös-Szekeres lemma on monotone subsequences.

Additional topics: the HEX game, score theorem.
