Query: Box-shaped matrices and the defining ideal of certain blowup surfaces   We study the defining equations of projective embeddings of the blowup of P^2
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.
