Monomiyal simetrik polinomların temel özelleşmesi ve döngüsel grupların grup determinantları

Özet (abstract)

Abstract In this paper, we study the principal specialization of monomial symmetric polynomials and investigate the special values of these polynomials at $$\begin{aligned} \zeta _{(n,k)} := ( 1, \zeta _n, \zeta _n^2, \dots , \zeta _n^{kn-1} ), \end{aligned}$$ ζ ( n , k ) : = ( 1 , ζ n , ζ n 2 , ⋯ , ζ n k n - 1 ) , where $$\zeta _n$$ ζ n is a primitive $$n$$ n th root of unity. We give explicit formulas for several classes of special values. We also show that these special values naturally appear as the coefficients in the expansion of the k th power of the circulant determinant of order n (the group determinant of the cyclic group of order n ). These results extend Ore’s formulas for the case $$k = 1$$ k = 1 . Furthermore, we determine the number of terms in the k th power of the group permanent of the cyclic group of order n . This extends Brualdi and Newman’s result for $$k = 1$$ k = 1 .
