Content and the Time Line of the Course


  1. (21.09.)
    Introductory lecture (First chapter): course information, set operations, cartesian product, power set, sequences, their sums and products,
  2. (28.09)
    Holiday - classes are canceled
  3. (5.10.)
    Second chapter is on simple arrangements and selections as permutations, k-permutations and combinations. Also we define arrangements and selections with repetitions as permutations with repetitions, combinations with repetitions and k-permutations with repetitions. We state two basic counting principles - the addition principle and the multiplication principle. ALso we mention the method of double counting. All complemented with simple examples.
  4. (12.10.)
    Lecture on probability: motivation problems, sample space, event, probability function, uniform probability, independent events, conditional probability, random variable, expected values.
  5. (19.10.)
    Lecture on proofs: basics of logic, propositions, connectives, quantifiers, different techniques of proofs, principle of mathematical induction.
  6. (26.10.)
    Lecture on relations: definition of the term relation, properties of relations, equivalence relation, partial ordering relation, mappings, permutations
    Also we will finish the topic of proofs including exercises.
    Worksheet 06 - Proofs by Mathematical Induction, by counting (DIM_ws_06.pdf)
  7. (2.11.)
    Completion of the lecture on relations + Inclusion exclusion principle
    For reading the chapter on algorithms for discrete structures is available here. dim_lecture07.pdf
    First lecture on graph theory, graphs, parity principle, Havel-Hakimi theorem, graph isomorphisms, implementation of graphs.
  8. (9.11.)
    Connectivity of graphs, searching through a graph, higher degrees of connectivity.
  9. (16.11.) lectures and discussions are canceled by the university president(rector) due to official ceremony event (vědecká rada)
