## Unique factorisation in noncommutative monoids
We consider right cancellative monoids C in which every nonunit can be
written as a product of atoms (irreducible elements) with such factorisations
satisfying a uniqueness property, and with C having the property that
for any element c, the partially ordered set of principal left ideals containing
Cc is a distributive lattice. We call such a monoid a We also make some remarks about the inverse hulls of these monoids. |
