Infinite products in monoids. (English) Zbl 0601.20061
For any monoid M in a certain class containing the abelian monoids and the groups, a monoid structure is constructed on some quotient set of $$M^{{\mathbb{N}}}$$, the set of all $${\mathbb{N}}$$-indexed sequences in M. Moreover this monoid is endowed with infinitary products extending its binary law in a natural way. Applications of these constructions in set theory and computer science are outlined.
