The finiteness of relative homological dimensions

  • Published: 29 May 2026
  • Let $ R $ be an Artin algebra, $ \mathrm{mod}R $ be the category of finitely generated right $ R $-modules, and let $ F $ be a sub-bifunctor of $ \mathrm{Ext}^{1}_{R}(-, -) $. In this paper, we introduce the notion of the $ F $-extension dimension for $ \mathrm{mod}R $. We further establish the relationships for the finiteness among the $ F $-extension dimension, $ F $-finitistic dimension and $ F $-Igusa-Todorov dimension.
