On the Decomposition Theorems for C*-Algebras.

Elliott dimension drop interval algebra is an important class among all C*-algebras in the classification theory. Especially, they are building stones of A H D algebra and the latter contains all AH algebras with the ideal property of no dimension growth. In this paper, the authors will show two decomposition theorems related to the Elliott dimension drop interval algebra. Their results are key steps in classifying all AH algebras with the ideal property of no dimension growth. [ABSTRACT FROM AUTHOR]
