The Bourbaki degree of the syzygy module of 2 $\times$ 4 matrices

Marcos Jardim, Felipe Monteiro, Abbas Nasrollah Nejad

We introduce and study the Bourbaki degree as a numerical invariant for \(2 \times 4\) matrices $\hat{I}˜$ of homogeneous polynomials over a polynomial ring \(R = k[x_1, \dots, x_n]\). T…
