Finite generation of the symbolic Rees ring of a space monomial prime ideal of a 3-dimensional weighted polynomial ring is a very interesting problem. Negative curves play important roles in finite generation of these rings. We are interested in the

Consider the blow-up Y of a weighted projective plane at a point in the open orbit over a field of characteristic 0. We assume that there exists a curve C on Y such that C^2

For a Mori dream space X, the Cox ring Cox(X) is a Noetherian $\mathbb {Z}^{n}$ -graded normal domain for some n > 0. Let C(Cox(X)) be the cone (in $\mathbb {R}^{n}$ ) which is spanned by the vectors $\boldsymbol {a} \in \mathbb {Z}^{n}$ such that Co

The aim of this manuscript is to discuss the Hilbert–Kunz functions over an excellent local ring regular in codimension one. We study the shape of the Hilbert–Kunz functions of modules and discuss the properties of the coefficient of the second h

The aim of this paper is to define the notion of the Cohen- Macaulay cone of a Noetherian local domain R R and to present its applications to the theory of Hilbert-Kunz functions. It has been shown by the second author that with a mild condition on R

Let R be a Cohen–Macaulay local domain. In this paper we study the cone of Cohen–Macaulay modules inside the Grothendieck group of finitely generated R-modules modulo numerical equivalences, introduced in Chan and Kurano (The cone spanned by maxi

Considering the Grothendieck group modulo numerical equivalence, we obtain the finitely generated lattice $\overline{G_0(R)}$ for a Noetherian local ring $R$. Let $C_{CM}(R)$ be the cone in $\overline{G_0(R)}_{\Bbb R}$ spanned by cycles of maximal Co
