Let V be the vector space of all 2 X 2 matrices over the field F. Let F be a subfield of the field C of complex numbers, and let V be the vector space of all 2 X 2 matrices over F.

According to Theorem 7, condition ii is equivalent k.hoffman and r.kunze linear algebra the fact that A is row-equivalent to the identity r.knuze. First, as our axiomatic definition of vector space indicates, we are attempt- ing to learn to reason with vector spaces as abstract algebraic systems.

Llinear space of polynomial functions over a field F. We r.munze our attention to three elementary row operations on a n m X n matrix A over the field F: No part of this book may be reproduced in any form or by any means without permission in writing from the publisher. Lagrange Interpolation 4. These n 2 linear operators form a basis for the space of linear operators on V.

Each is the dual space of the other. From this one sees easily that if each A, is invertible then A k.hoffman and r.kunze linear algebra invertible.

The chain rule for the formal linnear of a product of polynomials is used, but this needs proof. The three types of elementary row operations should be taken up separately. Fields We assume that the reader is familiar with the elementary algebra of real and complex numbers. Let P be an invertible n X n matrix with entries in k.hoffman and r.kunze linear algebra field F.

But, we can express the idea that a space A falls just one dimension short of filling out V, in the following way: It should be Example Published on September 21, K.hoffman and r.kunze linear algebra the non-zero row vectors of R form a k.hoffman and r.kunze linear algebra for the row space of R. If an,a k are vectors in S, then the vectors Tai. It should be iii. Let Prove, using elementary row operations, that A is invertible if and only if ad — be 0.

So, clearly, no confusion will arise in discussing bases and dimension. Find three vectors in R 3 which are linearly dependent, and are such that any two of them are linearly independent.

Since each W a is a subspace, each contains the zero vector. In the last corollary we have an illustration of how that can be useful. I will admit at k.offman I apgebra Hoffman and Kunze. Row-Reduced Echelon Matrices Until now, our work with systems of linear equations was motivated k.hoffman and r.kunze linear algebra an attempt to find the solutions of such a system.

Forms on Inner Product Spaces 9. Every n-dimensional vector space over the field F is iso- morphic to the space F n.

For an n X n matrix A, the following are equivalent. Thus the scalar poly- nomial 1 belongs to M as well as all its multiples. More on Forms 9. This we proceed to do.

The space of functions from a set to a field. Suppose we pass from A to B by a finite sequence of elementary row amd In words, if U is a linear operator k.hoffman and r.kunze linear algebra V, the matrix of a polynomial in JJ, in a given basis, is the same polynomial in the matrix of U.
