Abstract AR
سوف نشتق شروطا متكافئة سيكون بوساطتها لكل عنصر في فئة أبدالية غطاء X-أحادي و غلاف X-فوقي، على التوالي، عندما يكونX صفا من العناصر مغلقا تحت التمديد، و بشكل خاص، عندما يكونX صف امتداد عمودي نوني لصف عناصر معطاة.
سنعطي تطبيقات على فئات المعايير و المعايير المصاحبة.
Abstract EN
We establish equivalent conditions under which every object in an Abelian category has a monic X-cover and an epic X-envelope respectively, when X is a class of objects closed under extensions and, more particularly, an n-th Ext-orthogonal class of a given class of objects.
We give applications to categories of modules and comodules.
