Finitistic weak dimensions of pullbacks
WebThe corresponding left finitistic dimensions can be defined similarly. We now introduce another right "global" dimension r. IFD(R) defined as ... For relations with finitistic and weak dimensions, we have Theorem 3.2. Let R be any ring, then 1. FWD(R) ~ r. IFD(R) ~ WD(R). Proof. It suffices to prove 1. FWD(R) ~--< r. WebAbstract.

WebJul 3, 2024 · Abstract. The theory of finitely generated relative (co)tilting modules has been established in the 1980s by Auslander and Solberg, and infinitely generated relative tilting modules have recently been studied by many authors in the context of Gorenstein homological algebra. In this work, we build on the theory of infinitely generated … WebMay 20, 2014 · In this paper, we study homological dimensions of algebras linked by recollements of derived module categories, and establish a series of new upper bounds and relationships among their finitistic or global dimensions. This is closely related to a longstanding conjecture, the finitistic dimension conjecture, in representation theory and …
WebJun 4, 2024 · A closer look shows that for some of them the validity hinges on the strength of torsion-freeness in R which in turn is closely related to one of the finitistic projective and weak dimensions of the classical ring Q of quotients of R. This interesting fact was observed by Bazzoni–Herbera; in their paper (Bazzoni and Herbera, Isr J Math 174: ... WebJan 1, 2010 · Firstly, under weak assumptions on the noise coefficient, we prove the existence of a pullback attractor in L²(RN)×L²(RN) by using the tail estimate method and …
WebMar 16, 2024 · The small finitistic dimension $\fPD (R)$ of is defined to be the supremum of projective dimensions of -modules with finite projective resolutions. In this paper, we characterize a ring with $\fPD (R)\leq n$ using finitely generated semi-regular ideals, tilting modules, cotilting modules of cofinite type or vaguely associated prime ideals. WebFeb 11, 2024 · 11. The question "What precisely is finitistic reasoning?" has a long and tangled history, and a short answer would inevitably be misleading. So let me point to something a bit more substantial. A very good place to start is Richard Zach's extremely helpful encyclopedia article on Hilbert's Program, here.
