Abstract
Let be an -primitive -normal element over , where is a prime power and is a positive integer. The minimal polynomial of is referred to be the -primitive -normal polynomial of over . In this article, we study the existence of an -primitive -normal polynomial over such that the last two coefficients are prescribed. In this context, first, we prove a sufficient condition which guarantees the existence of such a polynomial. Further, we compute all possible exceptional pairs in case of -primitive -normal polynomials for .
