“…It is an open problem to compute the dimension of polynomial rings over Krull domains in general. In this vein, Bouvier conjectured that "finitedimensional Krull (or more particularly factorial) domains need not be Jaffard" [8,15]. In Figure 1, a diagram of implications places this conjecture in its proper perspective and hence shows how it naturally arises.…”

This article consists of a collection of open problems in commutative algebra. The collection covers a wide range of topics from both Noetherian and non-Noetherian ring theory and exhibits a variety of research approaches, including the use of homological algebra, ring theoretic methods, and star and semistar operation techniques. The problems were contributed by the authors and editors of this volume, as well as other researchers in the area.

“…In the current paper, we offer direct and self-contained proofs using techniques and basic results from commutative ring theory. Early and recent developments on prime spectra and dimension theory are to be found in [3,5,6,7,29,30,31,34,35] for the special case of tensor products of k-algebras, and in [1,11,17,22,24,26,27] for the general case. Any unreferenced material is standard, as in [24,26].…”

Abstract. Let k be a field. This paper investigates the embedding dimension and codimension of Noetherian local rings arising as localizations of tensor products of k-algebras. We use results and techniques from prime spectra and dimension theory to establish an analogue of the "special chain theorem" for the embedding dimension of tensor products, with effective consequence on the transfer or defect of regularity as exhibited by the (embedding) codimension given by codim(R) := embdim(R) − dim(R).

Essential domains and two conjectures in dimension theory

Abstract: Abstract. This note investigates two long-standing conjectures on the Krull dimension of integer-valued polynomial rings and of polynomial rings in the context of (locally) essential domains.
