本文推广了Kirchberg给出的可分离核\cst-代数的性质,证明了在紧可度量空间X上给定一个可分离核C*-代数的单可分离连续域a,该C(X)-代数a与平凡连续域C(X;O_2)的单C(X)-子代数同构于范数一投影C(X;O_2)的像。
We extend in this paper the characterisation of a separable nuclear \cst-algebra given by Kirchberg proving that given a unital separable continuous field of nuclear C*-algebras A over a compact metrizable space X, the C(X)-algebra A is isomorphic to a unital C(X)-subalgebra of the trivial continuous field C(X;O_2), image of C(X;O_2) by a norm one projection.
