Abstract
Let f: X → S be a morphism of complex or real spaces, and P a property of homomorphisms of local rings. Consider the set ℙ(f) of points x∈X for which the induced map of local rings O S,f(x) → O X,x has property P. In this chapter we give a criterion for ℙ(f) being constructible (resp., Zariski open) in X. Moreover, we verify this criterion for a wide class of properties P.
