comment Unique factorization consequence
It is pricipal ideal domain (Lang uses principal entire ring so I just translated wrong from Croatian), also, I don't have any condition on b. I was not sure "right inclusion" is good expression so I just thougth it would be clear from second paragraf which inclusion it is :-P

Thank you, I just used same notation as for factor groups (Lang in Algebra used something similar so I thought it is coprehensive)

comment Unique factorization consequence
b is from ring R, any not null element. And I write +(pb) because it is element of quotient module.

comment Direct products, direct sums and coproducts in category of groups
I'm lost in meaning of symbols. Is G*H free product group? Apropriate commitative property- what do you mean by that? If I've understood corectly you used universal property of coproduct to show my definition is not isomorphic to free product. But what if we dont know about free product? Why would direct or weak direct product fail definition of coproduct?
