An Invariant Subspace Theorem
for every rational function ƒ with poles off K. In this note it is shown that any operator for which the spectrum is a spectral set has a nontrivial invariant subspace. In [6] von Neumann introduced the notion of spectral set and showed that if T has II T\\ = 1 then the closed unit disc, D"~, is a spectral set for T. For this reason any operator whose spectrum is a spectral set is called a von ...
متن کاملA sampling theorem for shift-invariant subspace
A sampling theorem for regular sampling in shift invariant subspaces is established. The sufficient-necessary condition for which it holds is found. Then, the theorem is modified to the shift sampling in shiftinvariant subspaces by using the Zak transform. Finally, some examples are presented to show the generality of the theorem.
متن کاملThe common invariant subspace problem and Tarski’s theorem
This article presents a computable criterion for the existence of a common invariant subspace of n×n complex matrices A1, . . . , As of a fixed dimension 1 ≤ d ≤ n. The approach taken in the paper is model-theoretic. Namely, the criterion is based on a constructive proof of the renowned Tarski’s theorem on quantifier elimination in the theory ACF of algebraically closed fields. This means that ...
متن کاملLomonosov’s Invariant Subspace Theorem for Multivalued Linear Operators
The famous Lomonosov’s invariant subspace theorem states that if a continuous linear operator T on an infinite-dimensional normed space E “commutes” with a compact operator K 6= 0, i.e., TK = KT, then T has a non-trivial closed invariant subspace. We generalize this theorem for multivalued linear operators. We also provide some applications to singlevalued linear operators.
