Abstract

We investigate all kinds of the Hilbert function of the Artinian quotient of the coordinate ring of a linear star configuration in <TEX>${\mathbb{P}}^2$</TEX> of type 3 (or 3-general points in <TEX>${\mathbb{P}}^2$</TEX>). As an application, we prove that such an Artinian quotient has the SLP.
