k modulo r(x) and denote this by n∈C_(k,r(x)). So we give another definition: C_k={UC_(k,r(x))|r(x) are all monic irreducible polynomials of degree k (k0) over Z_n}. 本文引入n是k階摸r(x)的Carmichael數(shù)的定義,全體這樣的數(shù)記為集C_(k,r)(x),由此給出k階Carmichael數(shù)集:C_k={∪C_(k,r)(x)|r(x)過全體Z_n上的首一k次不可約多項(xiàng)式}。 The Irreducible Polynomials over Finite Fields 有限域上的不可約多項(xiàng)式 In chapter 1, we suppose n is a posite, Zn is residue class ring mod n, r(x) ∈Z_n[x] is a monic irreducible polynomialof degree k(k 0). 在
