A characterization of descent and effective descent morphisms in the category w-Cpo of w-chain complete posets is given. It turns out that effective descent morphisms in w-Cpo are exactly those effective descent morphisms in Pos with the property of lifting w-chains and their upper bounds.

Abstract
A characterization of descent and effective descent morphisms in the category w-Cpo of w-chain complete posets is given. It turns out that effective descent morphisms in w-Cpo are exactly those effective descent morphisms in Pos with the property of lifting w-chains and their upper bounds.File in questo prodotto:
