Abstract

Let q be an odd prime power. We prove that a planar function f from 𝔽q to itself can be written as an affine Dembowski–Ostrom polynomial if and only if the projective plane derived from f is a commutative semifield plane.

Keywords: Planar function; relative difference set; semifield plane
