What is a bijective linear transformation?

    A bijective linear transformation A:U ?? V is called an isomorphism. Two vector spaces for which there is an isomorphism are called isomorphic. Here are several useful statements, using the notion of an isomorphism, whose proofs are left as exercises. LetA:U ?? Vbe a linear transformation between ?nite dimensional vector spaces over F.

What is a linear transformation?

    22Vsuch that w 1= T(v 1) and w 2= T(v 2). Now consider T1( w 1+ fv 2) = T 1( T(v 1) + fT(v 2)) = T1(T( v 1) + T(fv 2)) = T1(T( v 1+ fv 2)) = v 1+ fv 2since T1T= Id V = T1(w 1) + fT 1(w 2) ) T1is a linear transformation Nomenclature 10.13. A linear transformation is also called a vector space homomorphism.

How do you prove that T1 is a linear transformation?

    Then T1: W!V is also a linear transformation. Proof. Let w 1;w 22W. Since Tis surjective, there exists v 1;v 22Vsuch that w 1= T(v 1) and w 2= T(v 2). Now consider T1( w 1+ fv 2) = T 1( T(v 1) + fT(v 2)) = T1(T( v 1) + T(fv 2)) = T1(T( v 1+ fv 2)) = v

How does a linear transformation determine L(X) for any vector Xin R3?

    a linear transformation completely determines L(x) for any vector xin R3. We collect a few facts about linear transformations in the next theorem. Theorem 3.1. Let Lbe a linear transformation from a vector space V into a vector space W. Then 1. L(000) = 00
