Rees algebras and their varieties
Publicationes Mathematicae Debrecen, 2022Following a paper of the reviewer [Publ. Inst. Math., Nouv. Sér. 29(43), 229-239 (1981; Zbl 0491.08002)], a subalgebra B of an algebra A is called a Rees subalgebra whenever there exists a congruence \(\theta\) on A such that \(\in \theta\) if and only if either \(x=y\) or both x, y are elements of B.

Summary: We study Rees algebras of modules within a fairly general framework. We introduce an approach through the notion of Bourbaki ideals that allows the use of deformation theory. One can talk about the (essentially unique) generic Bourbaki ideal \(I(E)\) of a module \(E\) which, in many situations, allows one to reduce the nature of the Rees ...

Rees algebras and gröbner bases
Communications in Algebra, 1990This paper deals with the following problem. Robbiano showed in [9] that standard bases, Grobner bases, Macaulay bases are all instances of the same general situation. In this paper, we develop this philosophy from the point of view of the Rees algebra R of a ring A w.r.t. a filtration F given on A.

The S2-Closure of a Rees Algebra
Results in Mathematics, 1993In this article, the authors show the following: Theorem 1.3. Let \(A\) be a Noetherian ring with canonical module \(\omega_ A\), and suppose that \(A\) is generically a Gorenstein ring. Then \(B=\text{Hom}_ A(\omega_ A,\omega_ A)\) is the minimal extension of \(A\) with the property \((S_ 2)\). Theorem 1.6.

On the structure of Noetherian symbolic rees algebras
Manuscripta Mathematica, 1990Let A be a Noetherian unmixed local ring, \(I\subset A\) an ideal, \(S\subset A\) a multiplicative system such that \(I\cap S=\emptyset\) and \(I^{(n)}:=A\cap I^ nA_ S\), \(n\in {\mathbb{Z}}\). If \(\ell (I^{(n)})=ht(I^{(n)})\) for a certain \(n\geq 1\), \(\ell (I)\) denotes the analytic spread of I, then the ring \(R_ I:=\oplus_{n\geq 0}I^{(n)} \) is ...
