Abstract
Besides giving a survey of some basic structures and ideas in K-theory and cyclic cohomology for non-commutative algebras, we describe a new way to realize algebras of abstract differential forms, over a given algebra A, and their “quantum” deformations. For this we use subalgebras and quotients of an algebra A[D, F] obtained from A by adjoining two additional elements D, F. This is closely related to the notion of a Fredholm module.
