Abstract
A univariate polynomial with non-constant term is called self-reciprocal if its sequence of coefficients reads the same backwards. A formula is known for the number of monic irreducible self-reciprocal polynomials of a given degree over a finite field. Every self-reciprocal polynomial of even degree 2n over a field can be written as the product of the nth power of x and a polynomial of degree n in x + 1/x. We study the problem of counting the irreducible polynomials over a finite field that are a product of the nth power of h(x) and a polynomial of degree n in the rational expression g(x)/h(x).
