This work describes the fundamental principles， problems， and methods of classical mechanics. The maiattentiois devoted to the mathematical side of the subject. The authors have endeavored to give aexpositiostressing the working apparatus of classical mechanics. The book is significantly expanded compared to the previous edition. The authors have added two chapters othe variational principles and methods of classical mechanics as well as otensor invariants of equations of dynamics. Moreover， various other sections have beerevised， added or expanded. The maipurpose of the book is to acquaint the reader with classical mechanics as a whole， iboth its classical and its contemporary aspects.
