Buchsbaum Stanley--Reisner rings with minimal multiplicity

Naoki Terai, Ken-ichi Yoshida

In this paper, we study non-Cohen--Macaulay Buchsbaum Stanley--Reisner rings with linear free resolution. In particular, for given integers $c$ , $d$ , $q$ with $c \geq 1$ , $2 \le q \…

Hilbert-Kunz multiplicity of three-dimensional local rings

Kei-ichi Watanabe, Ken-ichi Yoshida

In this paper, we investigate a lower bound (say $s_{H K} (p, d)$ ) on Hilbert-Kunz multiplicities for non-regular unmixed local rings of Krull dimension $d$ with characteristic $p > 0$ .…

Minimal Hilbert-Kunz multiplicity

Kei-ichi Watanabe, Ken-ichi Yoshida

In this paper, we ask the following question: what is the minimal value of the difference $e_{H K} (I) - e_{H K} (I^{'})$ for ideals $I^{'} \supseteq I$ with $l_{A} (I^{'} / I) = 1$ ? In order to answ…

Notes on Hilbert-Kunz multiplicity of Rees algebras

Kazufumi Eto, Ken-ichi Yoshida

In this paper, we estimate the Hilbert-Kunz multiplicity of the (extended) Rees algebras in terms of some invariants of the base ring. Also, we give an explicit formula for the Hil…
