Properties of derivative
Marková, Hana ; Zelený, Miroslav (advisor) ; Hencl, Stanislav (referee)
In the bachelor thesis we relate the concepts of derivative, the Darboux pro- perty and the function of the Baire class one. It is shown that each derivative has Darboux property and is of the Baire class one. Furthermore, we characterize the functions of the Baire class one using their associated sets. We introduce the concept of Zahorski classes and put them in connection with the functions of the Baire class one with the Darboux property. At the end of the thesis, we prove the Clarkson-Denjoy theorem.
Continuous mappings and fixed-point theorems
Vondrouš, David ; Holický, Petr (advisor) ; Zelený, Miroslav (referee)
This thesis deals with images of compact convex sets under a continuous mapping. We will show a combinatorial proof of famous Brouwer's fixed-point theorem based on Sperner's lemma. Later, this theorem will be applied for proving Brouwer's invariance of domain theorem, which asserts that image of an open subset of an euclidean space under a continuous mapping is open too. Then we will compare this proof with another proof using Borsuk's theorems. Their proof is more complicated, nevertheless it turns out that Borsuk's theorems give stronger results. One of them is, for instance, an analogy of the Darboux property for continuous mappings in an multidimensional space. 1
