If f: R!Sis a smoothable morphism of commu-tative Q-algebras such that Shas nite Tor-dimension over R, then the cotangent complex L f is of … WebLocal complete intersection morphisms. In Divisors, Section 31.21 we have defined 4 different types of regular immersions: regular, Koszul-regular, H_1 -regular, and quasi-regular. In this section we consider morphisms f : X \to S which locally on X factor as.
