Hyers-Ulam稳定性是Banach空间和Quasi-Banach空间中函数方程的重要性质.研究二阶线性微分方程的Hyers-Ulam稳定性,证明了线性微分方程y″-λ2y=f(x)具有Hyers-Ulam稳定性.
The Hyers-Ulam stability is the important property of functional equations in Banach spaces and Quasi-Banach spaces.The Hyers-Ulam stability of second order linear differential equations was studied and it is proved that differential equation y″-λ2y=f(x) has Hyers-Ulam stability.
