Axiomatické teorie množin

Abstract

Thesis focuses on axiomatic set theories. There are clearly described and processed the most famous theories - Zermelo-Fraenkel set theory, Gödel-Bernays set theory and Kelley-Morse set theory. In introduction is described the construction of logical theory with the definition of basic concepts and principles. There is also summarized and explained the cause of formation the axiomatic set theory and why naive set theory was not sufficient. Next chapters focus on proofs of individual theorems in specific theories. One of these chapters focuses on the rationale, why we can say that the Kelley-Morse set theory is stronger than Zermelo-Fraenkel set theory. Another chapter describes, how is possible to limit Gödel-Bernays set theory to theory with a finite number of axioms, although this theory is normally considered as infinitely axiomatized. The last chapter is dedicated to important proofs of unequivocalness of axiom of choice and the continuum hypothesis with Zermelo-Fraenkel set theory.
