Operator algebras and non-commutative geometry is one of the most exciting and active research areas in mathematics Contributing authors are top experts in the field, making this subseries unique Comprehensive coverage of the field Cyclic homology was introduced in the early eighties independently by Connes and Tsygan. They came from different directions. Connes wanted to associate homological invariants to K- homology classes and to describe the index pair• ing with K-theory in that way, while Tsygan was motivated by algebraic K-theory and Lie algebra cohomology. At the same time Karoubi had done work on characteristic classes that led him to study related structures, without however arriving at cyclic homology properly speaking. Many of the principal properties of

2004, XIII, 137 p. cyclic homology were already developed in the fundamental article of Connes and in the long paper by Feigin-Tsygan. In the sequel, cyclic homology was recognized quickly by many specialists as a new intriguing structure in homological algebra, with unusual features. In a Printed book first phase it was tried to treat this structure as well as possible within the traditional Hardcover framework of homological algebra.
