Kernel (algebra) - Wikipedia
en.wikipedia.org › wiki › Kernel_(algebra)The kernel is usually denoted as ker T, or some variation thereof: Since a linear map preserves zero vectors, the zero vector 0V of V must belong to the kernel. The transformation T is injective if and only if its kernel is reduced to the zero subspace. The kernel ker T is always a linear subspace of V.
Kernel (algebra) - Wikipedia
https://en.wikipedia.org/wiki/Kernel_(algebra)Let V and W be vector spaces over a field (or more generally, modules over a ring) and let T be a linear map from V to W. If 0W is the zero vector of W, then the kernel of T is the preimage of the zero subspace {0W}; that is, the subset of V consisting of all those elements of V that are mapped by T to the element 0W. The kernel is usually denoted as ker T, or some variation thereof: Since a linear map preserves zero vectors, the zero vector 0V of V must belong to the kernel. Th…

https://es.wikipedia.org/wiki/Kernel_(álgebra)Sean V y W espacios vectoriales sobre un campo (o más generalmente, módulos sobre un anillo) y sea T una aplicación lineal de V sobre W. Si 0W es el vector cero de W, entonces el núcleo de T es la preimagen del subespacio cero {0W}; es decir, el subconjunto de V que consta de todos los elementos de V que T asigna al elemento 0W. El núcleo generalmente se denota como ker T, o con alguna variación del mismo:
