SUMMARY

The discussion centers on the concept of generalized eigenspaces and their invariance under a linear operator T in finite-dimensional vector spaces over the complex numbers. The generalized eigenspace for an eigenvalue y is defined as the set of all vectors v in V such that there exists a j ≥ 1 for which (T - yI)^j(v) = 0. The term "invariant" in this context refers to the property that the generalized eigenspace remains unchanged under the action of the operator T.

Hey,
Is the generalized eigenspace invariant under the operator T? Let T be finite dimensional Linear operator on C(complex numbers).
My understanding of the Generalized Eigenspace for the eigenvalue y is:
"All v in V such that there exists a j>=1, (T-yIdenitity)^j (v) = 0." plus 0.
thanks
