摘要
“在本文中,我们证明了一个有趣的结果,关于线性泛函方程$g(\varphi(x))=a(x)\bullet g(x)$在完备度量群上的广义Hyers-Ulam稳定性,该结果是由S.M. Jung, D. Popa和M.T. Rassias在2014年给出的。此外,我们给出了可以用给定误差近似的函数的一个表征,通过上述线性方程的解。我们的结果也与G.H. Kim和thm.r assias最近关于Psi泛函方程稳定性的结果有关。
"Fixed points and the stability of the linear functional equations in a single variable"
"In this paper we prove that an interesting result concerning the generalized Hyers-Ulam stability of the linear functional equation $g(\varphi(x))=a(x)\bullet g(x)$ on a complete metric group, given in 2014 by S.M. Jung, D. Popa and M.T. Rassias, can be obtained using the fixed point technique. Moreover, we give a characterization of the functions that can be approximated with a given error, by the solution of the linear equation mention above. Our results are also related to a recent result of G.H. Kim and Th.M. Rassias concerning the stability of Psi functional equation."
