二阶线性微分方程解的零点与增长性

On Zeros and Growth of Solutions of Second Order Linear Differential Equations

Manisha Saini, Sanjay Kumar

摘要:

对于二阶线性微分方程$f''+A(z)f'+B(z)f=0$,当$ A(z)$和$B(z)$在某种限制条件下是超越整函数时,我们建立了所有非平凡解都是无穷级的.此外,我们还证明了这些解有无穷多个零点。同时,我们将这些结果推广到高阶线性微分方程。

英文摘要:

For a second order linear differential equation $f''+A(z)f'+B(z)f=0$, with $ A(z)$ and $B(z)$ being transcendental entire functions under some restriction, we have established that all non-trivial solutions are of infinite order. In addition, we have proved that these solutions have infinite number of zeros. Also, we have extended these results to higher order linear differential equations.
