Local rings math
Did you know?
In mathematics, more specifically in ring theory, local rings are certain rings that are comparatively simple, and serve to describe what is called "local behaviour", in the sense of functions defined on varieties or manifolds, or of algebraic number fields examined at a particular place, or prime. Local algebra is … Zobacz więcej A ring R is a local ring if it has any one of the following equivalent properties: • R has a unique maximal left ideal. • R has a unique maximal right ideal. • 1 ≠ 0 and the sum of any two non-units in R is a non-unit. Zobacz więcej Commutative case We also write (R, m) for a commutative local ring R with maximal ideal m. Every such ring … Zobacz więcej • Discrete valuation ring • Semi-local ring • Valuation ring • Gorenstein local ring Zobacz więcej • All fields (and skew fields) are local rings, since {0} is the only maximal ideal in these rings. • The ring $${\displaystyle \mathbb {Z} /p^{n}\mathbb {Z} }$$ is a local ring (p prime, n ≥ 1). The unique maximal ideal consists of all multiples of p. Zobacz więcej 1. ^ Krull, Wolfgang (1938). "Dimensionstheorie in Stellenringen". J. Reine Angew. Math.
