Abstract
A conjecture of Niho states that under certain assumptions the Fourier transform of the function Tr (xd) on F2n ,where d = (2tk1) /(2k +1), has a spectrum with at most five values. We present a counterexample to this conjecture, and the theory behind finding it.
We use the theory of quadratic forms over F2.
