You need to have "zapocet" to take the exam. The exam is oral and its content is captured in the sylabus.
"Zapocet" is given for active participation on the seminar. |

1. A concept of a topological space Open and closed sets; interior and closure; neighborhood systems; base of topology, base of neighborhoods of a point; countable weight and countable character, separability; convergence of sequences and nets (* of filters) and Hausdorff spaces (* T_0-, T_1-spaces); continuous mappings; examples of metrizanle and non-metrizable spaces.
2. Operations on topological spaces Subspace, sum and quotient, product; projective (weal, initial) generation, inductive (strong, final) generation; preserving properties; countable product of metrizable (completely metrizable, compact metrizable) spaces, Hulbert cube.
3. Completely regular spaces - embedding into a power of reals Embedding lemma (diagonal product); complete regularity and its preserving by products and subspaces; embedding into Tichonov cube (power of reals); embedding of separable metrizable space into Hilbert cube (* metrizablity of T_3-spaces with countable base).
