Combinatorial structure of low degree rational curves on a smooth Hermitian surface
Norifumi Ojiro
A smooth Hermitian surface is a projective surface isomorphic to the Fermat surface of degree 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 -Hermitian surface is a surface projectively isomorphic over to the Fermat surface of degree , where is an algebraic closure of a finite field with $q^…
Rational curves on a smooth Hermitian surface
Norifumi Ojiro
We study the set of nonplanar rational curves of degree on a smooth Hermitian surface of degree defined over an algebraically closed field of characteristic $…
A -dimensional extremal Type II lattice with no -frames
Norifumi Ojiro
We construct a -dimensional extremal Type II lattice not having any subsets consisting of orthogonal minimal vectors, and determine the automorphism group. This lattice gi…
The trace of modular forms and its application to number theory
Norifumi Ojiro
We provide a generalization of an algebraic linear combination for the trace of certain elliptic modular forms, and through specializing the expression at a suitable pair consistin…
