Letbe an abelian category. A subcategoryofis called a resolving subcategory ifis closed under extensions and kernels of epimorphisms and contains all projective objects of. In this paper, we consider the-resolution dimensions and special-precovers for a resolving subcategoryofMany results in Araya et al.
