The chapter ends with a dis- cussion of semi-simple operators, to round out the analysis of a single operator. The Prime Factorization of a Polynomial Chapter 5.

Let F be a subfield of the complex numbers llnear let V be the space of poly- nomial functions over F. For the matrix A of Exercise 2, find elementary matrices E h Ei.

These spaces have the same dimension, and so if we want to prove a theorem about the dimension of the solution space, it is immaterial which space we choose to discuss. This shows that S is a linearly dependent set. The space of functions from a set to a field. Throughout the book we have included a great variety of examples of the important concepts which occur. From Theorem 2 it follows that if S is any collection of vectors in V, then there is a smallest subspace of V which contains S, that is, a sub- space which contains S and which is contained in every other subspace containing S.


The first statement is evident from the symmetry of the definition. If V is a vector space, a hyperspace in V is a maximal proper subspace of V.

If we then perform on A’ a sequence of elementary row operations which leads from A to R, it will Sec. Bases and Dimension We turn now to the task of assigning a dimension to certain vector spaces. With the usual operations of addition and multiplication, the set of integers satisfies all of the conditions l – 9 except condition 8. For we believe a mathe- matics course should not give science, engineering, or social science students a hodgepodge of techniques, but should provide them with an understanding of basic mathematical concepts.

Let addition and scalar multiplication be defined as in Example 3. There are a few simple facts which follow almost immediately from the definition of a vector space, and we proceed to derive these. Let V be a vector space. If So spans W, then S 0 is a basis for W and we are done. Let F be the field of complex numbers. Two examples of row-reduced echelon matrices are the n X n identity matrix, and the m X n zero matrix 0 m ‘”, in which all entries are 0.

Row-reduction of the coefficient matrix provides us with a systematic method of finding this subspace. If so, we must be able to find T ei. Let m and n be positive integers and let F be a field.

Bases and Dimension 40 2.

This product we denote by A 3. The Algebra of Polynomials 4. If the column matrix T, with entries ti.

Prove that n is even. The matrix P above is precisely the matrix of the operator U in the ordered basis ffi. The point of this example is to show that we can give an explicit and reasonably simple description of all linear trans- formations from F m into F n.


Let F be any field and let S be any non-empty set. Show that a[, a 20: 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. These n 2 linear operators form a basis for the space of linear operators on V.

We shall now give an example of an infinite basis. The set of integers: If ft spans W, fine. This shows that the null space of T is the zero subspace, i.

Equivalence Relations A. These equations are instances of the general systemand using them we may tell at a glance whether a given vector lies in W.

One can also describe an m X n row-reduced echelon matrix R as follows.

These functionals are also linearly independent. In order to describe in a precise way the relation between polynomials and polynomial functions, m.hoffman need to define the product of two polynomial functions.

This observation leads us to one of the most fundamental facts concerning systems of homoge- neous linear equations.

Let F be a subfield of the complex numbers or a field of characteristic zero and let V be the space of polynomial functions over F. Let C 2X 2 be the complex vector space of 2 X 2 matrices with complex entries. Let V be the space of all polynomial functions over F. This would defeat our purpose, for two reasons.
