We study some properties of left product of two subcategories: one coreective and one reective in the category of local convex topological vectorial Hausdorff spaces. In this work on examined the situation generated by a structures of factorization (P¹¹; I¹¹) with certain properties, allowing to prove that the left product of some coreective subcategories with any P¹¹ - reective subcategory is one and the same. In addition, be indicated examples of coreectors and reectors functors which commutes..    

Vom studia unele proprietăţi ale produsului de stânga a douâ subcategorii: una coreectivă si una reectivă din categoria spatiilor topologice Hausdoff vectoriale local convexe. In acest articol se va examina situatia generata de structurile de factorizare (P¹¹; I¹¹) cu anumite proprietati, care va permite sa demonstram ca produsul de stanga a unor subcategorii coreective cu orice P¹¹ - subcategorie reectiva este una si aceiasi.  In plus, vor  fi indicate example de functori coreectori si reectori care comuta.
