Abstract

We prove an efficient version of the Wagner’s theorem on almost invariant subspaces (see $\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=1608090}{[5]}$) and deduce some consequences in the context of Galois extensions.

几乎不变的子空间和算子

我们在几乎不变的子空间上证明了瓦格纳定理的一个有效版本(参见$\href{https://mathscinet.ams.org/mathscinet/relay-station?mr=1608090}{[5]}$)，并在伽罗瓦扩展的背景下推导了一些结果。
