Socle degrees, Resolutions, and Frobenius powers

Andrew R. Kustin, Bernd Ulrich

We first describe a situation in which every graded Betti number in the tail of the resolution of $\frac{R}{J}$ may be read from the socle degrees of $\frac{R}{J}$ . Then we apply the abo…

Rational Normal Scrolls and the Defining Equations of Rees Algebras

Andrew R. Kustin, Claudia Polini, Bernd Ulrich

Consider a height two ideal, $I$ , which is minimally generated by $m$ homogeneous forms of degree $d$ in the polynomial ring $R = k [x, y]$ . Suppose that one column in the homogeneous…
