Nonlinarity of Boolean functions and hyperelliptic curves
Eric Férard, François Rodier
We study the nonlinearity of functions defined on a finite field with 2^m elements which are the trace of a polynomial of degree 7 or more general polynomials. We show that for m o…

Newton stratification for polynomials: the open stratum
Régis Blache, Eric Férard
In this paper we consider the Newton polygons of -functions coming from additive exponential sums associated to a polynomial over a finite field $\F_q$. These polygons define a…
