Subespacios invariantes, sección 39 del Halmos

We define the concept of an invariant subspace under an operator T from V to V and give examples. We show that an operator can lack invariant subspaces. We define the concept of an invariant subspace under a family of operators and explain how invariant subspaces simplify the matrix representation of an operator. This concludes section 39 of Halmos's text, which we highly recommend purchasing here: https://amzn.to/3ARyNdO.
