Abstract
We investigate the KK-lifting problem for generalized dimension drop interval algebras (with possibly different dimension drops at the endpoints). It turns out that there exist KK-elements between two such algebras which preserve the Dadarlat-Loring order structure on K-theory with coefficient, but fail to be lifted to a homomorphism between the algebras.
