Linear mapping linear algebra
Nettet25. aug. 2024 · A consequence of a map being linear is that the transformation is completely determined by where it takes the basis vectors. You can recognize this as a results of the ‘gridlines’ staying parallel, since if you know where the transformation takes the unit vectors, you can construct the skewed gridlines and thus the entire … NettetComposition of linear maps. by Marco Taboga, PhD. The composition of two or more linear maps (also called linear functions or linear transformations) enjoys the same linearity property enjoyed by the two maps being composed. Moreover, the matrix of the composite transformation is equal to the product of the matrices of the two original maps.

NettetKernel (linear algebra) 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.

In modern mathematics, the presentation through vector spaces is generally preferred, since it is more synthetic, more general (not limited to the finite-dimensional case), and conceptually simpler, although more abstract.
