For \(0<s<1\), let \(\Lambda \subset {\mathbb {D}}\) be a separated sequence such that \(\sum _{z_n\in \Lambda }(1-|z_n|)^s \delta _{z_n}\) is an s-Carleson measure. In this paper, we show that there exist certain analytic functions A such that the second order complex differential equation \(f''+Af=0\) admits a non-trivial solution f whose zero-sequence is \(\Lambda \), where the solution f belongs to some Möbius invariant function spaces. We strengthen a previous result from the literature.

具有某些给定零的二阶复微分方程的解

对于\(0 <s <1 \),令\(\ Lambda \ subset {\ mathbb {D}} \)是一个分隔的序列,使得\(\ sum _ {z_n \ in \ Lambda}(1- | z_n |)^ s \ delta _ {z_n} \)s -Carleson度量。在本文中,我们证明存在某些解析函数A,使得二阶复数微分方程\(f''+ Af = 0 \)允许一个零序列为\(\ Lambda \)的非平凡解f,其中解f属于一些Möbius不变函数空间。我们加强了文献的先前结果。
