Subspaces of End(V) that can fix any vector If $W$ is closed under multiplication and contains any invertible element $\varphi$, then $1\in W$: 1 can be written as a linear combination of positive powers of $\varphi$, which is follows from the fact that $\varphi$ satisfies a polynomial with non-zero constant term (namely its characteristic polynomial) |
