Then there is precisely one m X n row-reduced echelon matrix over F which has W as its row space. Tn S there are distinct vectors m, a 2 k.hoftman. Since the rank plus the nullity is ft, the nullity is 0 precisely when the rank is ft. On one hand, we have structured the chapters, especially the more difficult ones, so that there are several natural stop- ping points along the way, allowing the instructor in a one-quarter or one-semester course to exercise a considerable amount liear choice in the subject matter.
Since the coordinates a: Test the following systems of equations as in Exercise 2. This is all so natural that the reader may find that he has been using this terminology already. Prove that T is the zero transformation if and only if A is the zero matrix. We do not want to dwell on this point; however, we should indicate why we adopt such a conven- tion.
If a is in V, let Ta be the n-tuple x h. The answer is easily seen to be yes. Every n-dimensional vector space over the field F is iso- morphic to the space F n. If T is any linear transformation from V into W, then T is g.kunze by its action on the vectors ay. The reader may judge for him- self which is a neater form of bookkeeping. If V is a vector space, the collection of all linear functionals on V forms a vector space in a natural way.
A set G; 2. Thus from and Theorem 7 of Chapter 1, it follows that P is invertible. A basis for V is a linearly inde- pendent set of vectors in V which spans the space V. We let F denote either the set of real numbers or the set of complex numbers. Let F be a subfield of the complex numbers and let V be the space of poly- nomial functions over F. Adn is the dual space of the other. Summary of Row-Equivalence In this section we shall utilize some elementary facts on bases and dimension in finite-dimensional vector r.kuzne to complete our discussion of row-equivalence of matrices.
Chapters 6 and 7 contain a discussion of the concepts which are basic to the analysis of a single linear transformation on a finite-dimensional vector space; the analysis of charac- teristic eigen values, triangulable and diagonalizable transformations; the con- cepts of the diagonalizable and nilpotent parts of a more general transformation, and the rational and Jordan canonical forms.

Now the leading non-zero entry of row 1 occurs in column k, that entry is 1, and every other entry in column k is 0. One can see at a glance that they are independent. This shows that S is a linearly dependent set.
The set of alvebra n X n matrices with matrix multiplica- tion as the operation is another example of a group.
That is, suppose that we are given w. We shall denote this vector space by F K.

Chapter 4 defines the algebra of polynomials over a field, the ideals in that algebra, and the prime factorization of a polynomial. Suppose So is a linearly independent subset of W. Let Y be a finite-dimensional vector o.hoffman over the field F, and let W be a subspace of V.
Suppose A is an m X n matrix over the field F. Theorem 1 helps to underscore the fact that the functions which are linear aalgebra extremely special. An elementary row operation is thus a special type of function rule e which associated with each m X n matrix A an m X n matrix e A. We should take special note of the fact that if T is a linear operator on V then we can compose T with T.
It is likely that the reader has studied calculus and has dealt there with linear combinations of functions; certainly this is so if he has studied differential equations. The polynomials 1, x. The dimension of a finite-dimensional space V is the largest n such that some n-tuple of vectors in V is linearly independent — and so on.

Thus we can define the trace of a linear operator on a finite-dimensional space to be the oinear of any matrix algebar represents the operator in an ordered basis.
Consider the linear operators E p – q which arose in the proof of Theorem 5: Since products of invertible matrices are invertible, we see that A is in- vertible if and only if R is invertible.
Since k is the nullity of T and n is the dimension of V, we are done. We shall eliminate it in general in the next theorem. We want to avoid becoming embroiled in a lengthy discussion of that axiom, so we shall not tackle annihilators for general vector spaces. The identity operator I Sec. Then V is the subspace spanned by the set S. Some people find it less awkward to carry along two sequences of matrices, one describing the reduction of A to the identity l.hoffman the other recording the effect of the same sequence of operations starting from the identity.
From this .hoffman follows, as in the proof of Theorem 3, that W is the sub- space spanned by the union of Wi, W 2. Elementary Canonical Forms 6. Since this concept will be so important to us, we shall review its definition. We assume it to an true for polynomials of degree to — 1. Then R is the m X n matrix which has row vectors p u.
Let F mXn be the set of all m X n matrices over the field F. We claim the first non-zero coordinate of 8 occurs in one of the columns k s.
Row-reduction of the coefficient matrix provides us with a systematic method of finding this subspace.
