Abstract

Let R := k[x1, x2, x3] be a 3-dimensional polynomial ring over a field k. We prove that a (x1, x2, x3)-primary monomial ideal in such a ring is *-simple if it has minimal multiplicity with respect to each of its fibers. We also survey the known classes of *-simple monomial ideals in rings of this type and show that this new class is distinct from other known classes.
