Reflective and coreflective subcategories
Given any additive category C with split idempotents, pseudokernels and pseudocokernels,
we show that a subcategory B is coreflective if, and only if, it is precovering, closed under …

[PDF][PDF] Some decomposition properties of injective and pure-injective modules
JL Garcia, NV Dung - 1994 - projecteuclid.org
It is well known that over a left Notherian ring any direct sum of injecive modules is again
injective, and every injective module is a direct sum of indecomposable modules. Faith [6] …
