摘要：

Consider a grade 2 perfect ideal I in R = k[x(1), ..., x(d)] which is generated by forms of the same degree. Assume that the presentation matrix phi is almost linear, that is, all but the last column of phi consist of entries which are linear. For such ideals, we find explicit forms of the defining ideal of the Rees algebra R(I). We also introduce the notion of iterated Jacobian duals. (C) 2016 Elsevier Inc. All rights reserved.
