Generalizations of self-reciprocal polynomials

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...

Generalizations of orthogonal polynomials

We give a survey of recent generalizations for orthogonal polynomials that were recently obtained. It concerns not only multidimensional (matrix and vector orthogonal polynomials) and multivariate versions, or multipole (orthogonal rational functions) variants of the classical polynomials but also extensions of the orthogonality conditions (multiple orthogonality). Most of these generalizations...

On the Zeros of a Family of Self-Reciprocal Polynomials

Some 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...

Research Article On Zeros of Self-Reciprocal Random Algebraic Polynomials

This paper provides an asymptotic estimate for the expected number of level crossings of a trigonometric polynomial TN (θ)= ∑N−1 j=0 {αN− j cos( j +1/2)θ + βN− j sin( j +1/2)θ}, where αj and βj , j = 0,1,2, . . . ,N − 1, are sequences of independent identically distributed normal standard random variables. This type of random polynomial is produced in the study of random algebraic polynomials w...
