Abstract

In this paper we compute the generators, the Hilbert function, and the Hilbert polynomial of the projective closure of affine lines which are parallel to the coordinate axes and pass through a lattice of points. We also consider the Cohen–Macaulay and seminormality property of their homogeneous coordinate ring. These lines are said to form a grid.
