Abstract

We study the defining equations of projective embeddings of the blowup of P² at a set of d+1 \choose 2 number of points in generic position. To do this, we first generalize the notion of a matrix, its ideal of 2x2 minors to that of a box-shaped matrix. Our work completes previous works of Geramita and Gimigliano.
