WebJan 6, 2024 · Give an example of a linear operator T: Q 3 → Q 3 having the property that the only T-invariant subspaces are the whole space and the zero subspace. My initial instinct is to go for rotations in three dimensions, but I can't seem to prove that that has no nontrivial T-invariant subspaces. WebThe study of linear operators then introduces an invariant equipped with nonzero dimensionality, the eigenvector. In this paper, we endeavor to study how these simple principles can be extended to a more abstract notion, the invariant subspace. We begin with some very elementary, motivating examples. 1.1.
