Mori dream spaces of Calabi-Yau type and the log canonicity of the Cox rings

Yujiro Kawamata, Shinnosuke Okawa

We prove that a Mori dream space over a field of characteristic zero is of Calabi-Yau type if and only if its Cox ring has at worst log canonical singularities. By slightly modifyi…

Characterization of varieties of Fano type via singularities of Cox rings

Yoshinori Gongyo, Shinnosuke Okawa, Akiyoshi Sannai +1

We show that every Mori dream space of globally -regular type is of Fano type. As an application, we give a characterization of varieties of Fano type in terms of the singularit…
