Abstract

top
We investigate factorization of elements in overrings of a half-factorial domain A in relation with the behaviour of the boundary map of A . It turns out that a condition, called C ⋆ , on the extension plays a central role in this study. We finally apply our results to the special case of A + X ⁢ B ⁢ X polynomial rings.
