Abstract

It is shown that for a map f ⁣:XYf \colon X \to Y of compact spaces the unital \ast-homomorphism C(f) ⁣:C(Y)C(X)C(f) \colon C(Y) \to C(X) is projective in the category Mor(C1)\operatorname{Mor}({\mathcal C}^{1}) precisely when XX is a dendrite and ff is either homeomorphism or a constant.
