Equivariant E-theory for C -algebras

Defines a notion of equivariant asymptotic morphism, and use it to define equivariant $E$-theory groups $E_G(A,B)$ which generalize the $E$-theory groups of Connes and Higson. This title develops the basic properties of equivariant $E$-theory, including a composition product and six-term exact sequences in both variables.
