Linear maps and basis of domain
Nettet26. mar. 2024 · The bottom line is that matrices serve as simpler representatives for linear mappings. Given an arbitrary linear mapping, we can fix basis for the domain and codomain and obtain a corresponding matrix representation for the mapping. Conversely, for a given choice of basis, each matrix can also be interpreted as a general linear map. NettetOften, a linear map is constructed by defining it on a subset of a vector space and then extending by linearity to the linear span of the domain. Suppose ... being B the matrix of the given basis. Therefore, linear maps are said to be 1-co- 1-contra-variant objects, or type (1, 1) tensors.

NettetFrom Linear Algebra done right, Axler. As I understand it, there are two key results here: the first is that for any Basis in V and any arbitrary set of vectors, we can find a "corresponding" linear map. But what exactly does come first? Do we have a set of basis vectors, and a linear map, and the corresponding mappings in W are unique? http://web.mit.edu/18.06/www/Fall14/Midterm3ReviewF14_Darij.pdf

A linear map (or linear transformation) between two vector spaces U and V is a function T: U → V for which the following properties hold: For any vectors u1, u2 ∈ U, we have that T(u1 + u2) = T(u1) + T(u2).
