The stable (Hurwitz) polynomials are important in the study of differential equations systems and control theory (see  and ). A property of these polynomials is related to Hadamard product. Consider two polynomials p,q ∈ R[x]: the Hadamard product (p × q) is defined as where Some results (see ) shows that if p,q ∈R[x] are stable polynomials then (p×q) is stable, also, i.e. the Hadamard product is closed; however, the reciprocal is not always true, that is, not all stable polynomial has a factorization into two stable polynomials the same degree n, if n> 4 (see ).In this work we will give some conditions to Hadamard factorization existence for stable polynomials.
