频繁超循环整函数的最优增长性

Optimal growth of frequently hypercyclic entire functions

David Drasin, Eero Saksman

摘要:

我们解决了一个由A提出的问题。Bonilla和K.- G. Grosse-Erdmann的方法是构造一个关于微分算子经常是超循环的整函数$f$,它满足$M_f(r)\leq\displaystyle ce^r r^{-1/4}$,其中$c>0$任意小.所获得的增长率是急剧的。当以平均$L^p$ -规范衡量时,我们还获得了最佳的增长结果。除此之外,证明应用了Rudin-Shapiro多项式和热核估计。

英文摘要:

We solve a problem posed by A. Bonilla and K.-G. Grosse-Erdmann by constructing an entire function $f$ that is frequently hypercyclic with respect to the differentiation operator, and satisfies $M_f(r)\leq\displaystyle ce^r r^{-1/4}$, where $c>0$ be chosen arbirarily small. The obtained growth rate is sharp. We also obtain optimal results for the growth when measured in terms of average $L^p$-norms. Among other things, the proof applies Rudin-Shapiro polynomials and heat kernel estimates.
