AI总结:
本文研究标量倍部分等距的紧扰动算子,证明其一个子类存在非平凡超不变子空间,并由此推出具有有限维零空间的部分等距的Schatten类扰动也具有非平凡超不变子空间。
摘要:
本文证明了一类标量倍部分等距的紧扰动的子类存在非平凡超不变子空间。随后,我们说明该类包含若干重要的算子类。作为推论,我们证明了具有有限维零空间的部分等距的Schatten类扰动具有非平凡超不变子空间。
英文摘要:
In this article, we prove the existence of a non-trivial hyperinvariant subspace for a subclass of compact perturbations of scalar multiple of a partial isometry. Later, we illustrate that this class contains several important classes of operators. As a consequence, we prove that a Schatten class perturbation of a partial isometry with finite-dimensional null space has a non-trivial hyperinvariant subspace.
