Geometric regularity of powers of two-dimensional squarefree monomial ideals

Dancheng Lu

Let $I$ be a two-dimensional squarefree monomial ideal of a polynomial ring $S$ . We evaluate the geometric regularity, $a_{i}$ -invariants for $i \geq 1$ of the power $I^{n}$ . It turns o…

On reduction number of products of ideals

Dancheng Lu, Tongsuo Wu

Let $R$ be a standard graded algebra over an infinite field $K$ and $M$ a finitely generated $\ZZ$-graded $R$ -module. Let $I_{1}, \dots I_{m}$ be graded ideals of $R$ . The fun…
