Normal reduction numbers for normal surface singularities with application to elliptic singularities of Brieskorn type

Tomohiro Okuma, Kei-ichi Watanabe, Ken-ichi Yoshida

In this paper, we give a formula for normal reduction number of an integrally closed $m$ -primary ideal of a $2$ -dimensional normal local ring $(A, m)$ in terms o…

Cohomology of ideals in elliptic surface singularities

Tomohiro Okuma

We introduce the the normal reduction number of two-dimensional normal singularities and prove that elliptic singularity has normal reduction number two. We also prove that for a t…
