On $m$ -ovoids of Symplectic Polar Spaces

Tao Feng, Ye Wang, Qing Xiang

In this paper, we develop a new method for constructing $m$ -ovoids in the symplectic polar space $\W(2r-1,\q)$ from some strongly regular Cayley graphs in \cite{Brouwer1999Journal}…

Linear representations of finite geometries and associated LDPC codes

Peter Sin, Julien Sorci, Qing Xiang

The {\it linear representation} of a subset of a finite projective space is an incidence system of affine points and lines determined by the subset. In this paper we use character…

A new family of Hadamard matrices of order $4 (2 q^{2} + 1)$

Ka Hin Leung, Koji Momihara, Qing Xiang

Let $q$ be a prime power of the form $q = 12 c^{2} + 4 c + 3$ with $c$ an arbitrary integer. In this paper we construct a difference family with parameters $(2 q^{2}; q^{2}, q^{2}, q^{2}, q^{2} - 1; 2 q^{2} - 2)$ …

Generalized constructions of Menon-Hadamard difference sets

Koji Momihara, Qing Xiang

We revisit the problem of constructing Menon-Hadamard difference sets. In 1997, Wilson and Xiang gave a general framework for constructing Menon-Hadamard difference sets by using a…
