Abstract
A bifurcus semigroup is a semigroup in which every nonunit nonatom can be written as the product of exactly two atoms. We generalize this notion to -furcus semigroups: every element that can be factored as the product of at least nonunits can be factored as the product of exactly atoms. We compute some factorization-theoretic invariants of -furcus semigroups that generalize the bifurcus results. We then define two variations on the -furcus property, one stronger (presumabaly strictly) and the other strictly weaker than the -furcus property.
