Krull versus global dimension in Noetherian P.I. rings

, 1984
The Krull dimension of any noetherian P.I. ring is bounded above by its global (homological) dimension (when finite).

Cultural and Economic Grievances and the Political Salience of Secessionism

Nations and Nationalism, EarlyView.
ABSTRACT Why does secessionism become politically salient at some times but recede at others? Existing work highlights how cultural and economic grievances can shape secessionism, but it explains less well when these claims elevate the salience of secessionism and why similar grievances matter in some contexts but not others.

Krull dimension of injective modules over commutative Noetherian rings

, 2005
Let R be a commutative Noetherian integral domain with field of fractions Q. Generalizing a forty-year-old theorem of E. Matlis, we prove that the R-module Q/R (or Q) has Krull dimension if and only if R is semilocal and one-dimensional.

Müller Glia–Vasculature Interactions in the Developing Retina

Glia, Volume 74, Issue 10, October 2026.
Retinal vascular layers form normally despite loss of cholinergic retinal waves. Müller glial processes contact endothelial tip cells early and form Aquaporin‐4‐enriched endfeet. Glial endfoot calcium signals are compartmentalized and occur largely independently of neural activity. ABSTRACT Coordinated signaling among neurons, glia, and the vasculature

Global dimension in Noetherian rings and rings with Gabriel and Krull dimension [PDF]

, 1992
In this paper we compute the global dimension of Noetherian rings and rings with Gabriel and Krull dimension by taking a subclass of cyclic modules determined by the Gabriel filtration in the lattice of hereditary torsion ...

Krull dimension of modules and involutive ideals

, 1995
In this paper we establish an upper bound for the Krull dimension of a module over a Weyl algebra in terms of a geometrical invariant of its characteristic variety, the involutive dimension.
