On atoms and their density in the monoid of monomial ideals
Abstract
We study the structure and distribution of atoms in the monoid ℳon(R) of nonzero monomial ideals of the polynomial ring R=K[X1,…, XN], with N≥ 2. We characterize the atoms with at most four minimal generators and introduce the density d(N,μ) of atoms among monomial ideals with μ minimal generators. For μ≤ 4, we prove the existence of this density and determine its asymptotic behavior as N→∞. In the bivariate case, we also obtain a uniform lower bound for the density of atoms in a divisor-closed submonoid of ℳon(R) generated by equigenerated ideals.
