有界级整函数列在无穷远处的增长性

The growth at infinity of a sequence of entire functions of bounded orders

Dang Duc Trong, Truong Trung Tuyen

摘要:

本文考虑有界级整函数序列$(P_n)$在无穷远处的增长性。我们的结果推广了\cite{trong-tuyen2}中亏格为零的整函数的增长性的结果.给定一个有界阶整函数序列$P_n(z)$,我们发现了一个近似最优的条件,用$P_n$的零点给出,对于$(k_n)$,我们对所有$z\in \mathbb C$都有\begin{eqnarray*} \limsup_{n\to\infty}|P_n(z)|^{1/k_n}\leq 1 \end{eqnarray*}(见定理\ref{theo5})。探索有界阶整函数序列的增长自然会导致一个极值函数,它类似于Siciak的极值函数(见第6节)。

英文摘要:

In this paper we shall consider the growth at infinity of a sequence $(P_n)$ of entire functions of bounded orders. Our results extend the results in \cite{trong-tuyen2} for the growth of entire functions of genus zero. Given a sequence of entire functions of bounded orders $P_n(z)$, we found a nearly optimal condition, given in terms of zeros of $P_n$, for which $(k_n)$ that we have \begin{eqnarray*} \limsup_{n\to\infty}|P_n(z)|^{1/k_n}\leq 1 \end{eqnarray*} for all $z\in \mathbb C$ (see Theorem \ref{theo5}). Exploring the growth of a sequence of entire functions of bounded orders lead naturally to an extremal function which is similar to the Siciak's extremal function (See Section 6).
