Self-reciprocal Polynomials Over Finite Fields
The reciprocal f ∗(x) of a polynomial f(x) of degree n is defined by f ∗(x) = xf(1/x). A polynomial is called self-reciprocal if it coincides with its reciprocal. The aim of this paper is threefold: first we want to call attention to the fact that the product of all self-reciprocal irreducible monic (srim) polynomials of a fixed degree has structural properties which are very similar to those o...
متن کاملFast Algorithms to Generate Necklaces, Unlabeled Necklaces, and Irreducible Polynomials over GF(2)
Many applications call for exhaustive lists of strings subject to various constraints, such as inequivalence under group actions. A k-ary necklace is an Ž . equivalence class of k-ary strings under rotation the cyclic group . A k-ary unlabeled necklace is an equivalence class of k-ary strings under rotation and permutation of alphabet symbols. We present new, fast, simple, recursive algoŽ . rit...

The main result of this paper is a sharp integral mean inequality for the derivative of a ‘self-reciprocal’ polynomial.
متن کاملSome Properties of Generalized Self-reciprocal Polynomials over Finite Fields
Numerous results on self-reciprocal polynomials over finite fields have been studied. In this paper we generalize some of these to aself reciprocal polynomials defined in [4]. We consider the properties for the divisibility of a-reciprocal polynomials, estimate the number of all nontrivial a-self reciprocal irreducible monic polynomials and characterize the parity of the number of irreducible f...
متن کاملOn the Hansen-Mullen conjecture for self-reciprocal irreducible polynomials
Let q be a power of an odd prime and let k, n ∈ N such that 1 < k ≤ n. We investigate the existence of self-reciprocal irreducible monic polynomials over Fq, of degree 2n and their k-th coefficient prescribed.
