(also nonabelian homological algebra)
For a left exact additive functor between abelian categories, an object is -acyclic if the right derived functor of has no cohomology on in positive degree
A resolution by -acyclic objects serves to compute the derived functor of . See at derived functor in homological algebra β Via acyclic resolutions
