Title
Solving x+x+... +x=a over $\mathbb {F}_{2^{n}}$.
Abstract
This paper presents an explicit representation for the solutions of the equation ${\sum }_{i=0}^{\frac kl-1}x^{2^{li}} = a \in \mathbb {F}_{2^{n}}$ for any given positive integers k, l with l|k and n, in the closed field ${\overline {\mathbb {F}_{2}}}$ and in the finite field $\mathbb {F}_{2^{n}}$ . As a by-product of our study, we are able to completely characterize the a’s for which this equation has solutions in $\mathbb {F}_{2^{n}}$ .
