In this chapter we digress from the presentation of dimension theory and use the results of Chapters 9 and 10 to analyze some codimension-1 phenomena. In particular, we shall study “invertible” modules; give a criterion for a

Studies in Soviet History and Society, how do the “fibers” . ⊗. .(.) vary as we vary the prime . of .? If . is flat over ., then as we have seen, there is some sense in which the fibers vary continuously. The main result below, Grothendieck’s generic freeness lemma, a consequence of the Noether normalization theorem, implies that if .
