给出了Hilbert空间中的闭算子在另一个Hilbert空间中具有Hyers-Ulam稳定性的充要条件。此外，我们还证明了闭算子稳定常数的存在性。我们还确定了稳定常数的下限。
We give some necessary and su-cient conditions in order that a closed operator in a Hilbert space into another have the Hyers-Ulam stability. Moreover, we prove the existence of the stability constant for a closed operator. We also determine the stability constant in terms of the lower bound.
