Shell sources and interpretation of extremally charged spacetimes
 Veselý, Jiří ; Žofka, Martin (advisor) ; Svítek, Otakar (referee)
The subject of study of this thesis is the so-called ECS spacetime. It originated as an extension to the Majumdar-Papapetrou solution for an infinite extremally-charged string (hence ECS). In the first part of the thesis, some general properties of the spacetime are examined. However, the main method of research is Israel formalism, which is used to find an alternate and more physically-elegant source of the spacetime in question. Nine different model scenarios are thoroughly investigated. In the end, we succeed in finding a single source that is not singular, does not necessitate the presence of exotic matter and has acceptable properties even in the Newtonian limit of weak gravitation: two infinite cylinders filled with Minkowski spacetime.
