Regular local rings were originally defined by Wolfgang Krull in 1937, but they first became prominent in the work of Oscar Zariski a few years later, who showed that geometrically, a regular local ring corresponds to a smooth point on an algebraic variety. Let Y be an algebraic variety contained in affine n-space over a perfect field, and suppose that Y is the vanishing locus of the polynomials f1,...,fm. Y is nonsingular at P if Y satisfies a Jacobian condition: If M = (∂fi/∂xj) is th… Witryna3 gru 2024 · Equivalent Definitions of Local Ring.

Witryna25 lis 2016 · 27. This question has been bugging me for a while and I can't seem to make sense of it on a clear conceptual level. The theory of local rings is given by taking the theory of rings and adding the axioms. ( 0 = 1) ⊢ ⊥ x + y = 1 ⊢ ∃ z: ( x z = 1) ∨ ∃ z: ( y z = 1) This theory is geometric and thus has a classifying topos S [ Local Rings]. Witryna25 mar 2024 · Abstract. Diamond proved a numerical criterion for modules over local rings to be free modules over complete intersection rings. We formulate a refinement of these results using the notion of Wiles defect.A key step in the proof is a formula that expresses the Wiles defect of a module in terms of the Wiles defect of the underlying …
