Abstract
In this paper, a new homological dimension of modules, co-
presented dimension, is defined. We study some basic properties of this
homological dimension. Some ring extensions are considered, too. For
instance, we prove that if S ≥ R is a finite normalizing extension and
SR is a projective module, then for each right S-module MS, the cop-
resented dimension of MS does not exceed the copresented dimension of
HomR(S,M).
