LINEAR TRANSFORMATIONS
... and TA (λx) = λTA (x) similarly. In some senses, matrices are the only examples of linear maps. Theorem 15. Suppose that V and W are vector spaces with bases {v 1 , . . . , v m } = A and {w 1 , . . . , wn } = B respectively, and suppose that T : V → W is a linear map. Let ai denote the vector T vi , ...

APPM 2360 17 October, 2013 Worksheet #7 1. Consider the space
... Consider R3 as vector space (n = 3). Then S = {(1, 0, 0), (0, 1, 0)} is linearly independent set of R3 . However, it is not a basis for R3 . That is because it has only 2 elements, but dim(R3 ) = 3 (c) TRUE An n × n matrix is row equivalent to In×n ⇐⇒ A is invertible ⇐⇒ rank(A) = n ⇐⇒ rank(A) = dim( ...

FAMILIES OF SIMPLE GROUPS Today we showed that the groups
... but finitely many of the other finite simple groups also fall into infinite families, and these families generally consist of invertible matrices over finite fields such as Fp (the integers mod p, p a prime). Later in the course we will learn that there is a finite field Fq of order q = pr , r ∈ N+ ...
