From the reviews: "The book is structured into three parts. The first part ... offers preliminary topics on general relativity. ... The second part is a comprehensive and accurate incursion in the mathematical background of relativity theory. ... The last part, entitled Gravitation, contains six chapters dealing with the Einstein equation ... cosmology and special topics. Interesting exercises with complete answers simplify the understanding of the presented material. The textbook is recommended to advanced graduates and researchers." (Ferenc Szenkovits, Studia Universitatis Babes-Bolyai, Mathematica, Vol. LV (4), December, 2010) "This book provides the reader with a very gentle introduction to the main ideas and concepts of general relativity. This work is particularly suitable for students who are interested in general relativity or are beginning to study this subject. Moreover, the author presents the reader with a number of problems and provides worked-out solutions, which will surely help the reader to obtain a deeper of interest to students who seek a smooth introduction to general relativity."
