Abstract

We address the conjecture of Durfee (Math Ann 232:85-98, 1978), bounding the singularity genus pg by a multiple of the Milnor number μ for an n-dimensional isolated complete intersection singularity. We show that the original conjecture of Durfee, namely (n+1)!· pg ≤ μ, fails whenever the codimension r is greater than one. Moreover, we propose a new inequality Cn,r · pg μ, and we verify it for homogeneous complete intersections. In the homogeneous case the inequality is guided by a 'combinatorial inequality', that might have an independent interest.
