关于实多项式Bohnenblust-Hille不等式

On the real polynomial Bohnenblust-Hille inequality

J. R. Campos, P. Jiménez-Rodríguez, G. A. Muñoz-Fernández, D. Pellegrino, J. B. Seoane-Sepúlveda

摘要:

Bayart等人最近证明了复多项式Bohnenblust-Hille不等式是次指数不等式.我们表明,真正的标量,这不再成立。此外,我们还证明了,如果$D_{\mathbb{R},m}$表示$m$ -齐次多项式的实Bohnenblust-Hille常数,则$\displaystyle\lim\sup_{m}D_{\mathbb{R},m}^{1/m}=2.$

英文摘要:

It was recently proved by Bayart et al. that the complex polynomial Bohnenblust--Hille inequality is subexponential. We show that, for real scalars, this does no longer hold. Moreover, we show that, if $D_{\mathbb{R},m}$ stands for the real Bohnenblust--Hille constant for $m$-homogeneous polynomials, then $\displaystyle\lim\sup_{m}D_{\mathbb{R},m}^{1/m}=2.$
