Termodynamika černých děr. Entropie a informace.
Liška, Marek ; Acquaviva, Giovanni (advisor) ; Scholtz, Martin (referee)
The aim of the thesis is to provide a review of black hole thermodynamics and its relation with concepts of entropy and physical information. We start by deriving the four laws of black hole thermodynamics in the context of classical general relativity. To supplement this, we use semiclassical limit of quantum mechanics to show that black holes radiate and have non-zero thermodynamic temperature. In the second part of the thesis we describe the concepts of the Shannon and von Neumann entropy and of physical information. Lastly, we discuss the use of these concepts in the context of black hole mechanics. 1

Comparison of fundamental information concepts and its consequences
Valový, Marcel ; Rosický, Antonín (advisor) ; Brixí, Radim (referee)
As for now, there exists no universal theory for understanding information. Therefore, in Information Society the term Information is often led to being misenterpreted and in contrary, things which are not an information are often interpreted as one. In consequences, threats opposed by use of Information technologies cannot be foreseen. This thesis, in its four theoretically oriented chapters, thoroughly describes the nature of information, not only its physical essentiality, but also its applicated state in human mind and societies, and puts it in contrast with that, what is not information. In fifth and ending chapter the thesis addresses consequences that emerge from the information of human into the Information Society and threats of totalitarian substance connected to the concept of Global mind, whose transformation into reality, despite us not recognizing it, has begun.
