Abstract:

For certain grade two perfect ideals, there is an expected description of the equations of the Rees algebra. In this paper, the Cohen–Macaulayness of the Rees algebra, numerical invariants of the ideal, and a condition on the minors of a presentation matrix of the ideal are shown to be related to the equations having this form.
