Let F denote a finite field of q elements. A Kakeya set (also called a Besicovitch set) in F is a set K ⊂ F such that K contains a line in every direction. More formally, K is a Kakeya set if for every x ∈ F there exists a point y ∈ F such that the line Ly,x ≜ {y + a ⋅ x∣a ∈ F} is contained in K. The motivation for studying Kakeya sets over finite fields is to try to better understand the more complicated questions regarding Kakeya sets in R. A Kakeya set K ⊂ R is a compact set containing a… CONTINUE READING
