R Bagherian, E Hosseini - Bulletin of the Iranian Mathematical Society, 2021 - Springer
Abstract Assume that (X, O _X)(X, OX) is an arbitrary scheme. The concept of the big (resp.
little) finitistic flat dimension FFD (X)(resp. fFD (X)) of X will be introduced. It is shown that if X …

[PDF][PDF] When the flat and Gorenstein flat dimensions coincide?
S Bouchiba - Colloq. Math, 2017 - researchgate.net
It is well known that, given a ring R, if M is an R-module such that pdR (M)<∞, then GidR
(M)= idR (M)(Holm, 2004). This shows in particular that if R is a Noetherian ring such that …
