WebMar 5, 2024 · The subspaces n u l l ( T) and r a n g e ( T) are invariant subspaces under T. To see this, let u ∈ n u l l ( T). This means that T u = 0. But, since 0 ∈ n u l l ( T), this implies that T u = 0 ∈ n u l l ( T). Similarly, let u ∈ r a n g e ( T). Since T v ∈ r a n g e ( T) for all v ∈ V, we certainly also have that T u ∈ r a n g e ( T).
