O carater de Chern-Connes para C${}^{\ast }$-sistemas dinamicos calculado em algumas algebras de operadores pseudodiferenciais

David P. Dias

Given a C${}^{\ast }$-dynamical system $(A,G,\alpha )$ one defines a homomorphism, called the Chern-Connes character, that take an element in $K_0(A)\oplus K_1(A)$, the K-theory groups of the…
