让pandq是一个一元双曲多项式,使得q5分开展开,成为pandq的bj(形式)。然后他的非负定和对称Sylvester矩阵与p。当E. Jannelli观察到这个事实时。我们给出了这一事实的一个简单证明,同时证明了S. Spagnolo引入的pandgive准对称子的Nuij近似的bsamizoutian族。给出了J. Leray用于严格双曲多项式的对称子与h的关系。
Letpandqbe a monic hyperbolic polynomials such thatqseparatespand letHbe the Bézoutian (form) ofpandq. ThenHis nonnegative definite and symmetrizes the Sylvester matrix associated withp. Whenthis fact is observed by E. Jannelli. We give a simple proof of this fact and at the same time prove that the family of Bézoutian of Nuij approximation ofpandgives quasi-symmetrizers introduced by S. Spagnolo. A relation connectingHwith the symmetrizer which was used by J. Leray for strictly hyperbolic polynomials is also given.
