Dimension and Hilbert-Samuel PolynomialsIn this section we present a characterization of dimension that yields other important invariants and that is well suited to computation using techniques to be developed in Chapter 15. Throughout we shall write . for a local ring with maximal ideal m. All modules will be finitely generated .-modules unless otherwise stated.掺和 发表于 2025-3-25 09:08:22

Roots of Commutative Algebrand 1893. Three major strands of nineteenth-century activity lie behind commutative algebra and are still its primary fields of application: number theory, algebraic geometry (the algebraic aspect really begins with Riemann’s “function theory”), and invariant theory. We shall say a little about developments in each.增长 发表于 2025-3-26 17:56:21
Localizationechnique of . reduces many problems in commutative algebra to problems about local rings. This often turns out to be extremely useful: Most of the problems with which commutative algebra has been successful are those that can be reduced to the local case.
