摘要：Let K denote a field. A polynomial f(x)∈K[x] is said to be decomposable over K if f(x)=g(h(x)) for some polynomials g(x) and h(x)∈K[x] with 1<deg(h)<deg(f). Otherwise f(x) is called indecomposable. If f(x)=g(xm) with m>1, then f(x) is said to be trivially decomposable. In this paper, we show that xd
