Singular points configurations on quotients of the projective plane by $1$ -foliations of degree $- 1$ in characteristic $2$

Tadakazu Sawada

In this paper, we classify the configurations of the singular points which appear on the quotients of the projective plane by the $1$ -foliations of degree $- 1$ in characteristic $2…

Quotients of smooth projective toric varieties by $μ_{p}$ in positive characteristics $p$

Tadakazu Sawada

In this paper we show that quotients of smooth projective toric varieties by $μ_{p}$ in positive characteristics $p$ are toric varieties.

Classification of globally F-regular $F$ -sandwiches of Hirzebruch surfaces

Tadakazu Sawada

Let $X$ be a smooth variety over an algebraically closed field of positive characteristic. An $F$ -sandwich of $X$ is a normal variety $Y$ through which the relative Frobenius morph…
