Point particle kinematics and light propagation in de Sitter spacetime
Michalík, Tomáš ; Hinterleitner,, Franz (referee) ; Larsen, Klaus Bering (advisor)
V této práci se zabýváme de Sitterovou speciální relativiou, která se odehrává v de Sitterově časoprostoru namísto Minkowského časoprostoru. Začínáme studií grupy symetrie de Sitterova časoprostoru. Snažíme se použít tyto poznatky k rozvinutí kinematiky v de Sitterově časoprostoru. Dále přezkoumáváme spojení mezi elektrodynamikou na pevně zvoleném časoprostoru a elektrodynamikou v makroskopickém médiu v plochém časoprostoru. Toto aplikujeme na de Sitterův časoprostor a hledáme index lomu sdruženého média.
Lie groups and their physical applications
Kunz, Daniel ; Kureš, Miroslav (referee) ; Tomáš, Jiří (advisor)
In this thesis I describe construction of Lie group and Lie algebra and its following usage for physical problems. To be able to construct Lie groups and Lie algebras we need define basic terms such as topological manifold, tensor algebra and differential geometry. First part of my thesis is aimed on this topic. In second part I am dealing with construction of Lie groups and algebras. Furthermore, I am showing different properties of given structures. Next I am trying to show, that there exists some connection among Lie groups and Lie algebras. In last part of this thesis is used just for showing how this apparat can be used on physical problems. Best known usage is to find physical symmetries to establish conservation laws, all thanks to famous Noether theorem.
