Let R be an Artin algebra, m o d R be the category of finitely generated right R-modules, and let F be a sub-bifunctor of E x t R 1 ( , ). In this paper, we introduce the notion of the F-extension dimension for m o d R. We further establish the relationships for the finiteness among the F-extension dimension, F-finitistic dimension and F-Igusa-Todorov dimension.
