(1) Note that if A is an m n matrix, then T : Rn Rm defined by T (x) = Ax for any vector x Rn is a linear transformation , yet for any non-zero vector b, x Ax + b does not define a linear transformation . b x (2) Note that both T1 (f ) = a f (x) dx and T2 (f ) = a f (x ) dx define linear transformation s, but T1 can be regarded as a linear transformation from C[a, b] to R, but T2 has a different codomain: it can be regarded as a linear transformation from C[a, b] to C[a, b]. The precise range of T2 is in fact a subspace of C[a, b]: T2 (C[a, b]) = {g C 1 [a, b] : g(a) = 0}. (3) Theorem 2.2 provides a method for finding a spanning set for the range R(T ) of a linear transformation T . Then the dimension and a basis of R(T ) can be found from the method of Theorem 1.9. (4) The dimension of R(T ) is related to the dimension of the domain and the dimension of the null space N (T ) through the dimension theorem, Theo ...

    Excerpt: ... function f (x) = mx that you might encounter in Math 201; our aim today is to consider it carefully. Since we have identified complex numbers with two dimensional real vectors, we may also think of Tm as being a function Tm : R 2 R 2 . Viewed in this way, the function is, in fact, a linear transformation (you may verify it if you like). Remember that any such linear transformation is defined by a 2 2 matrix Mm . What is the matrix Mm ? (If you don't remember how to find the matrix given by a linear transformation , ask me.) What is det(Mm ) and what is the geometric significance of this determinant in terms of m? 1 Note for Math 310 students: The association m Mm defines an isomorphism between the field of complex numbers and a sub-field of the ring of 2 2 matrices. This gives a way of describing the complex numbers that answers the sticky question "What is i?" 2. Now go to the web page: http:/ Here you will find a diagram, labelled "Part I," that allows you to ...

    Excerpt: ... MATH 110 Lecture Notes 3 GSI Carter June 25, 2008 1 Linear Transformation s Let V and W be vector spaces over a field F . Then a function T : V W is called a linear transformation if for every x, y V and every F , we have T (x + y) = T (x) + T (y) T (x) = T (x) Such a function can also be referred to as an F - linear transformation to indicate which field F is being used. Some examples: Multiplication by a matrix A. Differentiation. Integration on a fixed interval [a, b]. Theorem. Let T : V W be linear. Then the null space N (T ) is a subspace of V , and the range R(T ) is a subspace of W . 1 Theorem. Let T : V W be linear. Then T maps any generating set for V to a generating set for R(T ). Theorem. Let T : V W be linear. Then dim N (T ) + dim R(T ) = dim V. We define rank(T ) to be dim R(T ) and nullity(T ) to be dim N (T ). Theorem. Let T : V W be linear. Then T is one-to-one if and only if N (T ) = {0}. Theorem. A linear transformation is uniquely determined by its behavior on a ...

    Excerpt: ... Linear Algebra - Dr Stoy - 14 MT + 8 HT Linear algebra pervades and is fundamental to geometry (from which it originally arose), algebra, analysis, applied mathematics, statistics-indeed all of mathematics. The course has several aims. The first is to introduce students through a thorough study of two- and three-dimensional spaces to the general concept of a vector space, subspaces, and the ideas of linear dependence, independence, spanning sets, bases, dimension. A second aim is to introduce students to matrices and their applications to the algorithmic solution of systems of linear equations and to the study of linear transformation s of vector spaces. A third aim is to introduce determinants and their properties. A fourth aim is to introduce eigenvalue theory and some of its applications. Fourteen lectures in Michaelmas Term Introduction: examples of linear problems (e.g., system of linear equations, differential equations) and their solutions. Vectors in the plane and 3-space ...

    Excerpt: ... Math 250B 5.1 Linear Transformation s Summer 2007 Denition Let V and W be vector spaces. A mapping T from V into W is a rule that assigns to each vector v V exactly one vector w = T (v) in W . We denote such a mapping by T : V W . Denition Let V and W be vector spaces. A mapping T : V W is called a linear transformation from V to W if it satises the following: 1. T (u + v) = T (u) + T (v) for all u, v V . 2. T (cu) = c T (u) for all u V and all scalars c. A mapping that does not satisfy (either of) the conditions in the above denition is called a non linear transformation . Note that the above denition implies 1. T (0) = 0 2. T (v) = T (v) 3. T (c1 v + c2 u) = c1 T (v) + c2 T (u) for all linear transformation s T : V W , u, v V , c1 , c2 scalars. Example Which of the following are linear transformation s? 1. T : R3 R2 dened by T (x) = Ax, where A = 1 0 1 . 2 3 1 2. T : M2 (R) M2 (R) dened by T (A) = AT . 3. T : M2 (R) R dened by T (A) ...
