Chapter 5 Linear Transformations The Algebra of Linear TransformationsTheorem vector spaces over the fieldF. LetTandUbetwo Linear Transformations fromVintoW. The function(T+U)defined pointwiseby(T+U) (v) =Tv+Uvis a Linear transformation fromVintoW. Furthermore, ifs F, the function(sT)defined by(sT) (v) =s(Tv)is also a Linear transformation fromVintoW. The set of all Linear transformationfromVintoW, together with the addition and scalar multiplication defined above,is a vector space over the thatTandUare Linear transformation fromVintoW.
ible. For vector spaces, the relevant structure is given by vector addition and scalar multiplication. Since a linear transformation preserves both of these operation, it is also a vector space homomorphism. Likewise, an invertible linear transformation is a vector space isomorphism. 5.2 Linear Functionals on Vector Spaces Definition 5.2.1.
