Special apolar subset: the case of star configurations

Algebraic Geometry 2019-09-20 v3

Abstract

In this paper we consider a generic degree dd form F F in n+1n+1 variables. In particular, we investigate the existence of star configurations apolar to FF, that is the existence of apolar sets of points obtained by the n n -wise intersection of r r general hyperplanes of Pn \mathbb{P}^n . We present a complete answer for all values of (d,r,n)(d,r,n) except for (d,d+1,2)(d,d+1,2) when we present an algorithmic approach.
