Collinear triples in permutations

Liangpan Li

Let $α : F_{q} \to F_{q}$ be a permutation and $Ψ (α)$ be the number of collinear triples in the graph of $α$ , where $F_{q}$ denotes a finite field of $q$ elements.…

On the size of Nikodym sets in finite fields

Liangpan Li

Let $F_{q}$ denote a finite field of $q$ elements. Define a set $B \subset F_{q}^{n}$ to be Nikodym if for each $x \in B^{c}$ , there exists a line $L$ such that $L\cap B^c…

On the number of collinear triples in permutations

Liangpan Li

Let $α : Z_{n} \to Z_{n}$ be a permutation and $Ψ (α)$ be the number of collinear triples modulo $n$ in the graph of $α$ . Cooper and Solymosi had given by induction the bo…
