A characterization of weak (semi-)projectivity for commutative   C*-algebras
  We show that the spectrum X of a weakly semiprojective, commutative C*-algebra C(X) is at most one dimensional. This completes the work of S{\o}rensen and Thiel on the characterization of weak (semi-)projectivity for commutative C*-algebras.
