Gravitation in higher dimensions
Kubíček, Jan ; Pravdová, Alena (advisor) ; Žofka, Martin (referee)
The thesis starts with a brief introduction to the algebraic classificati- on of tensors and spacetimes in higher dimensions. Attempts to generalize the Goldberg-Sachs theorem are also discussed. There is a summary of main results for optical matrices of algebraically special spacetimes in higher dimensions. The optical matrix for a type III spacetime in six dimensions is found using Bianchi identities. A few properties of type III optical matrices in a general dimension are also found. Various properties of equations obtained from Bianchi identities for type III spacetimes are studied in appendices. 1

Probabilistic Spacetimes
Káninský, Jakub ; Svítek, Otakar (advisor) ; Žofka, Martin (referee)
Probabilistic Spacetime is a simple generalization of the classical model of spa- cetime in General Relativity, such that it allows to consider multiple metric field realizations endowed with probabilities. The motivation for such a generalization is a possible application in the context of some quantum gravity approaches, na- mely those using the path integral. It is argued that this model might be used to restrict the precision of the geometry on small scales without postulating discrete structure; or it may be used as an effective description of a probabilistic geometry resulting from a full-fledged quantum gravity computation.

Making use of Povídky malostranské in teaching literature at elementary school
Kalátová, Anna ; Klumparová, Štěpánka (advisor) ; Hausenblas, Ondřej (referee)
The first part of the thesis presents didactically transformed interpretation about Jan Neruda, his life and work, and about Povídky malostranské as a part of the complex. There is general information about the cycle of short stories. The process of creating of this work and also the themes are outlined here (distinctive features of Povídky malostranské), which could be used at school. Lessons can be focused on the characters, narrative style, or spacetime. In the following chapters there are the basic facts about Czech pubescent readers, the evaluation of structured interviews with primary school teachers about their experiences and the way how to work with Povídky malostranské there is summarized knowledge about the way how the authors handle the topic of Povídky malostranské of reading-books. The three model lessons based on the working with the texts (each lesson is focused on one of the distinctive features of this work) are the important part of this thesis. These lessons were taught at elementary school, therefore they are provided with the evaluation.
