摘要

Let $\u_{1\times n}$ , $\X_{n\times n}$ , and $\v_{n\times 1}$ be matrices of indeterminates, $\Adj \X$ be the classical adjoint of $\X$ , and $H(n)$ be the ideal $I_1(\u\X)+I_1(\X\v)+I_1(\v\u-\Adj \X)$ . Vasconcelos has conjectured that $H(n)$ is a perfect Gorenstein ideal of grade $2n$ . In this paper, we obtain the minimal free resolution of $H(n)$ ; and thereby establish Vasconcelos' conjecture.
