Abstract
It is shown that the Orlik-Terao algebra is graded isomorphic to the special fiber of the ideal I generated by the. (n - 1)-fold products of the members of a central arrangement of size n. This momentum is carried over to the Rees algebra (blowup) of I and it is shown that this algebra is of fiber-type and Cohen-Macaulay. It follows by a result of Simis and Vasconcelos that the special fiber of I is Cohen-Macaulay, thus giving another proof of a result of Proudfoot and Speyer about the Cohen-Macaulayness of the Orlik-Terao algebra.
