Bohnenblust-Hille不等式中常数的下界:实标量情形

Lower bounds for the constants in the Bohnenblust-Hille inequality: the case of real scalars

Diogo Diniz, Gustavo Muñoz-Fernández, Daniel Pellegrino, Juan B. Seoane-Sepúlveda

摘要:

Bohnenblust-Hille不等式是在1931年得到的,并且(在实标量的情况下)断言,对于每个正整数$N$和每个$m$ -线性映射$T:\ell_{\infty}^{N}\times...\times\ell_{\infty}^{N}\rightarrow \mathbb{R}$,有(\sum \limits_{i_{1},...,i_{m}=1}^{N}| T(e_{i_{^{1},.,e_{ i_{m} })|^{ \frac{2m}{m+1} })^{ \frac{m+1}{2m} } \leq C_{m} \VertT \Vert,对于某个正常数$C_{m}$。此后,几位作者获得了$C_{m}$值的上限估计值。然而,在这个简短的说明中提出的新颖之处在于,我们提供了$C_{m}$的下限(和非平凡的)。

英文摘要:

The Bohnenblust-Hille inequality was obtained in 1931 and (in the case of real scalars) asserts that for every positive integer $N$ and every $m$-linear mapping $T:\ell_{\infty}^{N}\times...\times\ell_{\infty}^{N}\rightarrow \mathbb{R}$ one has (\sum\limits_{i_{1},...,i_{m}=1}^{N}|T(e_{i_{^{1}}},...,e_{i_{m}})|^{\frac{2m}{m+1}})^{\frac{m+1}{2m}}\leq C_{m}\VertT\Vert, for some positive constant $C_{m}$. Since then, several authors obtained upper estimates for the values of $C_{m}$. However, the novelty presented in this short note is that we provide lower (and non-trivial) bounds for $C_{m}$.
