Witryna30 kwi 2024 · The null space isn't empty, but it is the zero space (the subspace consisting of only the origin). As to why a matrix is invertible if is has zero nullity, this comes back to what it means for a matrix (or more specifically a linear map) to be invertible. It means that you can reverse its effects. In mathematics, the kernel of a linear map, also known as the null space or nullspace, is the linear subspace of the domain of the map which is mapped to the zero vector. That is, given a linear map L : V → W between two vector spaces V and W, the kernel of L is the vector space of all elements v of V such that L(v) = … Zobacz więcej The notion of kernel also makes sense for homomorphisms of modules, which are generalizations of vector spaces where the scalars are elements of a ring, rather than a field.

Witryna23 lip 2024 · The former is a natural number, while the latter is a subspace of V, NOT in general a vector (unless the kernel is just 0). The phrase the rank of the kernel makes no sense; it only makes sense to talk about the rank of a transformation. Similar, the nullity of the rank also makes no sense.
