Combinatorial structure of low degree rational curves on a smooth Hermitian surface

Norifumi Ojiro

A smooth Hermitian surface $X$ is a projective surface isomorphic to the Fermat surface of degree $q + 1$ in positive characteristic. We study incidence relations of the rational cur…

Rational curves on a smooth Hermitian surface II: moduli and counting of certain infinite families

Norifumi Ojiro

A smooth $k$ -Hermitian surface $X$ is a surface projectively isomorphic over $k$ to the Fermat surface of degree $q + 1$ , where $k$ is an algebraic closure of a finite field with $q^…

Rational curves on a smooth Hermitian surface

Norifumi Ojiro

We study the set $R$ of nonplanar rational curves of degree $d < q + 2$ on a smooth Hermitian surface $X$ of degree $q + 1$ defined over an algebraically closed field of characteristic $…
