How to interpret Kafka? Criticism of the Czech reception of Kafka's work and an attempt a new approach
Soukup, Jiří ; Bílek, Petr (referee) ; Pokorný, Martin (advisor)
The point of departure of this thesis is a detailed research into Kafka's early periodical publications and into the earliest German reception connected to them. The Czech reception, not following until the first Kafka's book, is investigated here in several steps: desribed is as whole the Czech reception during Kafka's lifetime (1913-1923), at large the period before the February Coup d'état (1924-1948) and in a summarizing chapter we focus on the history of Kafka's reception until these days (1948-2010). The typological part of this thesis analyzes then in detail two different philosophical approaches to Kafka: the unsatisfactory Calasso's conception and an original understanding by Matěj Král. The aim is to distinguish productive lines of Kafka's philosophical interpretations through a substantial analysis and critique.

Existenční teorie pro velká data pro nestacionární proudění vazkopružných tekutin
Pušman, Jan ; Málek, Josef (advisor) ; Pokorný, Milan (referee)
In the present. work, we investiga te some evolutionary viscoelastic fluid models of Oldroyd type. The model consis of the incompressible Navier-Stokes equations coupled with transport equations for components of stress tensor. We provide a more detailed proof of the exis tence of weak solutions in case of space periodic boundary conditions following the original paper by Lion s and Masrnoudi. The proof is based on exploiting the propagation in time of the compactness of the solutions, i.e. the property that if we take a sequence of weak solution s which converges weakly and such that the corresponding initial conditions converge strongly, then the weak limit is also a solution.

Regularity of solutions of systems describing generalized Newtonian fluids
Tichý, Jakub ; Kaplický, Petr (advisor) ; Pokorný, Milan (referee)
We investigate properties of solutions of systems of nonlinear partial differential equations describing evolutionary flow of certain class of generalized Newtonian fluids including in particular various variants of the power-law models. We study the problem with perfect slip boundary conditions. The nonlinear elliptic operator, which is related to the stress tensor, has a p-potential structure. We focus especially on the case p = 2. The main part of the work deals with regularity of second space derivatives and overcoming new di±culties connected with usage of considered boundary conditions.

Macrobius and his influence on the neo-Platonic interpretation of myths
Hlaváček, Jakub ; Putna, Martin C. (advisor) ; Kratochvíl, Zdeněk (referee) ; Pokorný, Martin (referee)
The dissertation outlines the fundamental topics in Macrobius' poetics and philosophy which were to serve as the theoretical grounding for the literature of the Middle Ages and Renaissance. Our main focus was Macrobius' treatment of poetic modes imitations (imitatio) and its relation to a broader philosophical framework wherein poetic modes, viewed as ontological archetypes, represent the world of ideas. We have shown that imitation draws heavily on imagination, which in Late Antiquity became rather highly valued. We have seen that the creative treatment of a textual model (archetype) is rooted in the Stoic analogy of godly and human creative acts. The dissertation explains Macrobius' interpretation of myths and his arguments defending their use in philosophy. I believe that it was Macrobius' defence of the "truth of myths" (albeit we have seen that Macrobius was heavily drawing on Proclos here whose influence, however, was minimal) which lies at the heart of the medieval and Renaissance revival of interest in myths. Finally, we have discussed what role myths and other leading themes of the neo-Platonic and Stoic philosophy of Late Antiquity played in the alchemist literature of the Middle Ages and Renaissance.

On fluids with pressure-dependent viscosity flowing through a porous medium
Žabenský, Josef ; Pokorný, Milan (advisor)
Experimental data convincingly show that viscosity of a fluid may change significantly with pressure. This observation leads to various generalizations of well-known models, like Darcy's law, Stokes' law or the Navier-Stokes equations, among others. This thesis investigates three such models in a series of three published papers. Their unifying topic is development of existence theory and finding a weak solution to systems of partial differential equations stemming from the considered models.
