WebTo see that the kernel is a subgroup, we need to show that for any g and h in the kernel, g h is also in the kernel; in other words, we need to show that ρ ( g h) = 1. But that follows from the definition of a homomorphism: ρ ( g h) = ρ ( g) ρ ( h) = 1 ⋅ 1 = 1. We leave it to the reader to find the proof that the image is a subgroup of H.

WebFound. The document has moved here. WebKernel is used for any linear transformation while nullspace is only used with matrices. So if you have a matrix A, you can find N (A), but not ker (A) since a martix by itself is just an expression and not a linear transformation. Likewise, if you have T (x⃑) = A x⃑, then you can take ker (T), but not N (T).

WebSep 16, 2024 · The kernel of T, written ker(T), consists of all →v ∈ V such that T(→v) = →0. That is, ker(T) = {→v ∈ V: T(→v) = →0} It follows that im(T) and ker(T) are subspaces of W and V respectively. Proposition 5.7.1: Kernel and Image as Subspaces Let V, W be subspaces of Rn and let T: V → W be a linear transformation. http://ltcconline.net/greenl/courses/203/MatrixOnVectors/kernelRange.htm
