Letbe an extension-closed subcategory of a triangulated category such thatadmits a weak-cogenerator. We investigate finite resolutions by objects inand-resolution dimension of objects. It is shown that ifis also a weak-generator in, then any finite resolution by objects inof an object gives rise to another finite resolution such that one of the objects in the resolution belongs to, while all the rest objects are in. We establish two additive functors between additive quotient categories related toandwhenis further-injective. In particular, we show that both two functors possess certain adjointness and that one can characterize the objects with a finite resolution by objects inhaving a finite resolution by objects in(resp., when an object with a finite resolution by objects inbelongs to) by vanishing of the counit (resp., unit) of the adjunction with respect to one of these functors (resp., another one). For any object with a finite resolution by objects in, we construct a cellular tower with respect toand show that such a cellular tower can be used to detect the value of-resolution dimension provided thatis also closed under cocones.
