Irreducible polynomial finite field
WebThe point is that every element of F q n is a root of g ( x), so. g ( x) = ∏ α ∈ F q n ( x − α). Now an irreducible polynomial h ( x) over F q of degree n splits in distinct linear factors over F … Every polynomial over a field F may be factored into a product of a non-zero constant and a finite number of irreducible (over F) polynomials. This decomposition is unique up to the order of the factors and the multiplication of the factors by non-zero constants whose product is 1. Over a unique factorization domain the same theorem is true, but is more accurately formulated by using the notion of primitive polynomial. A primitive polynomial is a polynomial over a unique fact…
