چکیده
|
In this paper, we show that injectivity with respect to the class d of dense monomorphisms of an idempotent and weakly hereditary closure operator of an arbitrary category well-behaves. indeed, if m is a subclass of monomorphisms, m ∩ d-injectivity well-behaves. we also introduce the notion of (r, t)-injectivity in the category s-act, where r and t are hoehnke radicals, and discuss whether this kind of injectivity well-behaves.
