Dimension of complexes related to special Gorenstein projective precovers
Z Liu, J Li - Communications in Algebra, 2022 - Taylor & Francis
Let R be a ring and X a complex of R-modules. We investigate the relationship between the
dimensions Gppd (X) and Gpd (X) of X, where Gppd (X) is the dimension related to special …

Z Liu, M Pengju - Communications in Algebra, 2023 - Taylor & Francis
Let R be a ring and X a complex of R-modules. We give some characterizations of the
dimension of X related to special Gorenstein projective precovers. Let R be a ring such that …

[PDF][PDF] Relative cohomology dimensions of complexes based on degreewise cotorsion pairs
Z Liu, J LI, Z Wang - PUBLICATIONES MATHEMATICAE …, 2022 - researchgate.net
Let R be an associative ring with identity, and (A, B) a hereditary cotorsion pair generated by
a set in R-Mod. Then (dw A,(dw A)⊥) is a complete and hereditary cotorsion pair (we call it …
