We will consider the approximate diagonalization of homomorphisms from AH-algebras to C*-algebras of rational tracial rank one. Specifically, every homomorphism from a commutative C*-algebra to a C*-algebra of tracial rank one is approximately diagonalizable, but approximate diagonalization does not hold in general when we consider more general domains or codomains. We will look at special cases where approximate diagonalization does apply.
