Abstract
In this paper, we investigate special arrangements of lines in multiprojective spaces. In particular, we characterize codimension 2 arithmetically Cohen-Macaulay (ACM) varieties in P 1 × P 1 × P 1 , called varieties of lines. We also describe their ACM property from a combinatorial algebra point of view.
