On Segre products, $F$ -regularity, and finite Frobenius representation type

Anurag K. Singh, Kei-ichi Watanabe

We study the behavior of various properties of commutative Noetherian rings under Segre products, with a special focus on properties in positive prime characteristic defined using…

Gorensteinness for normal tangent cones of elliptic ideals

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

Let $A$ be a two-dimensional excellent normal Gorenstein local domain. In this paper, we characterize elliptic ideals $I \subset A$ for its normal tangent cone $G (I)$ to…
