Deformation rigidity of the double Cayley Grassmannian

Shin-young Kim, Kyeong-Dong Park

The double Cayley Grassmannian is a unique smooth equivariant completion with Picard number one of the 14-dimensional exceptional complex Lie group , and it parametrizes eight…

Kähler-Einstein metrics on smooth Fano toroidal symmetric varieties of type AIII

Kyusik Hong, DongSeon Hwang, Kyeong-Dong Park

The wonderful compactification of a symmetric homogeneous space of type AIII for each is Fano, and its blowup along the unique closed orbit is Fano if…

Greatest Ricci lower bounds of projective horospherical manifolds of Picard number one

DongSeon Hwang, Shin-young Kim, Kyeong-Dong Park

A horospherical variety is a normal -variety such that a connected reductive algebraic group acts with an open orbit isomorphic to a torus bundle over a rational homogeneous…

The second largest number of points of plane curves over finite fields

Masaaki Homma, Seon Jeong Kim

A basis of the ideal of the complement of a linear subspace in a projective space over a finite field is given. As an application, the second largest number of points of plane curv…

Weierstrass semigroups on double covers of genus four curve

S. J. Kim, J. Komeda

Let C be a complete non-singular irreducible curve of genus 4 over an algebraically closed field of characteristic 0. We determine all possible Weierstrass semigroups of ramificati…

The characterization of Hermitian surfaces by the number of points

Masaaki Homma, Seon Jeong Kim

The nonsingular Hermitian surface of degree is characterized by its number of -points among the irreducible surfaces over of degree $\sqrt{q} +…

Rational curves with many rational points over a finite field

Satoru Fukasawa, Masaaki Homma, Seon Jeong Kim

We study a particular plane curve over a finite field whose normalization is of genus 0. The number of rational points of this curve achieves the Aubry-Perret bound for rational cu…

Sziklai's conjecture on the number of points of a plane curve over a finite field II

Masaaki Homma, Seon Jeong Kim

We settle the conjecture posed by Sziklai on the number of points of a plane curve over a finite field under the assumption that the curve is nonsingular.

Nonsingular plane filling curves of minimum degree over a finite field and their automorphism groups: Supplements to a work of Tallini

Masaaki Homma, Seon Jeong Kim

Our concern is a nonsingular plane curve defined over a finite field of q elements which includes all the rational points of the projective plane over the field. The possible degre…
