Some results on Kähler modules

Abstract

Let k be an algebraically closed field of characteristic zero, R, S affine k-algebras and letΩ(q)(R/k) and Ω(q)(S/k) denote their universal finite Kähler modules of differentials over k. Our paper is concerned with the relationship between Ω(q)(R/k) and Ω(q)(S/k) when there is a ring homomorphism θ: R->S.
