摘要
We prove two conjectures of Branden on the real-rootedness of the polynomials Q(n)(x) and R-n(x) which are related to the Boros-Moll polynomials P-n(x). In fact, we show that both Q(n)(x) and R-n(x) form Sturm sequences. The first conjecture implies the 2-log-concavity of P-n(x), and the second conjecture implies the 3-log-concavity of P-n(x).
