** Relativity Theory** is an introduction into the concepts and mathematical methods of Einstein's theory. The first two parts are devoted to the special theory, while in Part 3 fundamentals of the general theory are summarized in simple terms. The mathematics relevant to this theory is explained in detail in Part 4 no prior knowledge of the Riemannian geometry by the reader is, therefore, required. Part 5 contains those aspects of the theory which follow from the equivalance principle alone, Einstein-equations being introduced only in Part 6. Central symmetrical space-time and gravitational waves are treated in Parts 7 and 8 respectively. Part of the text is presented in the form of problems (there is about a hundred of them) each of which is accompanied with a detailed solution. The notes at the end of the book contain mainly historical material.
