The Algebra of Polynomials We are now in a position to define a polynomial over the field F.

Suppose Vector Spaces Chap. In particular this is true when A is the Linear Equations Chap. Prove that W n is exactly the subspace of matrices which have trace zero. Perhaps the k.hoffmn fundamental technique for finding the solutions of a system of linear equations is the technique of elimination.

The Primary Decomposition Theorem Chapter 7. What is the basis for V, of which this is the dual?

Let V be the vector space of all polynomial functions from R into R which have degree less than or equal to 2. The reader should note that polynomials are not the same sort of objects as the polynomial functions on F ane we have discussed on several occasions. This is all so natural that the reader may find that he has been using this terminology already.

For transformations of one space into another the matrix depends upon two ordered bases, one for V and one for IF. We shall give other examples below. We restrict our attention to three elementary row operations on a n m X n matrix A over the field F: Let A and B be m X n matrices over the field F. Accordingly, the transformation T is determined by the mn scalars A via the formulas One algebrz also describe linearr m X n row-reduced echelon matrix R as follows.

The formal derivatives of a polynomial are useful in discussing mul- tiple roots. Then g is a linear combination of fi, Verify that the set of complex numbers described in Example 4 is a sub- field of C. Row-Reduced Echelon Matrices Until now, our work with systems of linear equations was motivated by an attempt to find the solutions of such a system. On the other hand, suppose A has a right inverse, i.

Matrix Multiplication 16 1.

In Examples 5 and 6, the final matrices in the sequences exhibited there are row-reduced matrices. We have already derived the facts we shall need. So, clearly, no confusion will arise in discussing bases and dimension.

We want to avoid becoming embroiled in a lengthy discussion of that axiom, so we shall not tackle annihilators for general vector spaces. It is now clear that R is uniquely determined by W.

Every m X n matrix A is row-equivalent to a row-reduced echelon matrix. Let f and g be non-zero polynomials over F.

Since each W a is a subspace, each contains the zero vector. The following is one of the most important results in linear algebra. More generally, how does one find the dimension of the subspace W spanned by these vectors? Linesr matrix A which is associated with T a,gebra Theorem 11 is called the matrix of T relative r.kuze the ordered bases ffi, ffik Note that Equation says that A is the matrix whose columns A h. In our definition of the vector r.knuze R 3the vectors are simply defined to be the triples xi, x 2x 3.

Let V be the vector space of all polynomial functions over the field of real numbers. If fi is in V, there is a unique scalar c such that 3 — ca is in N. Suppose one has a set F of objects x, y, z.

Thus the zero vector is in the intersection W, and W is algrbra. To prove the theorem it suffices to show that every subset S of V which contains more than m vectors is linearly dependent. Now there is a completely obvious isomorphism between F n and F nX1namely, Xi. Adjoining 0 to any basis of Wwe obtain a linearly independent subset of V.

When there is no chance of confusion, we may simply refer to the vector space as V, or when it is desirable to specify the field, we shall say V is a vector space over the field F.

If so, describe explicitly all solutions. In addition, we would like to thank the many students and colleagues whose per- ceptive comments led to this revision, and the staff of Prentice-Hall for their patience in dealing with two authors caught in the throes of academic administra- tion. If C is the field of complex numbers, which vectors in C 3 are linear combina- tions of 1, 0, —10, 1, 1and 1, 1, 1? Let F be a subfield of the complex numbers.

Let us verify that F[x] is an algebra. Can you give an example of such a linear transformation TT Often, when we assume F is a subfield of C, what we want to guaran- tee is that F is a field of characteristic zero; but, in a first exposure to linear algebra, it is usually better not to worry too much about charac- teristics of fields.
