Abstract

In this article, we establish a sufficient condition for the existence of primitive element α\Fm\alpha\in \Fm is such that f(α)f(\alpha) is also primitive element of \Fm\Fm and Tr\Fm/\F(α)=βTr_{\Fm/\F}(\alpha)=\beta, for any prescribed β\F\beta\in\F, where f(x)=ax2+bx+c\Fm(x)f(x)= ax^2 + bx + c\in \Fm(x) such that b24ac0b^2-4ac\neq 0. We conclude that, for m5m\geq 5 there is only one exceptional pair (q,m)(q,m) which is (2,6)(2,6).
