For, havingdone so, they will understand both the power and the limitation of thegeneral theory and they will be better equipped to devise specific tech-niques to attack particular problems as they arise. This text has developed from my experience in teaching courses inelementary real analysis at the University of Illinois since Myaudience has ranged from well-prepared freshman students to graduatestudents; the majority in these classes are usually not mathematicsmajors. Generally they have taken at least the equivalent of threesemesters of non-rigorous calculus, including multiple integrals, vectorcalculus, line integrals, infinite series, and the like.

This set A fails to be open in R, since it contains the point O. If we define A 1 and B 1 by. If one feels sufficiently familiar with the rational field Q, one cari define real numbers to be special subsets of Q and define addition, multiplication, and order relations between these subsets in such a way as to obtain a complete ordered field, elements of real analysis bartle pdf.

Prove that if F is an ordered field in which every non-empty set which has an upper bound also has a supremum, then F is an Archimedean field. Use Exercise 7. It is to be noted that one of these sets contains its supremum,. We could decide in favor of one of these two representations, but it is not necessary to do so. The Derivative in Rp, Directional derivative, partial derivatives, the derivative, the Chain Rule, the Mean Value Theorem, interchange of the order of differentiation, Taylor's Theorem Returning to Figure 1. The entire text provides about the right amount of material for two semesters at this level. As seen before, the real number system is a field which satisfies certain additional properties. In Section 6, we make the final step by addmg the completeness property. In connection with the latter, it is important to realize that the word or is being used in the inclusive sense that is customary in mathematics and logic. For simplicity, we shall employ the term interval regardless of the dimension of the space. If a set B contains a non-void closed set, must the interior BO see Exercise 8. Can the intersection of an infinite collection of open sets be a non-empty com- pact set? Describe the geometrical relations among the complex numbers z, z and liz for z r O.

Thus the complex number system C has the same elements as the two-dimensional space R2. Prove that a closed interval in Rp is a closed set. Hint: every infinite set has a denumerable subset. The following steps cari be used as an outline. It would be desirable to have the students take a semester either in linear or modern algebra before this analysis course, for such a back- ground facilitates the study of rigorous analysis. If a sequence has a limit, we say that the sequence is convergent. Bartle - The Elements of Real Analysis Any subsetof a jnite set is jinite. Since F is a sub- set of Fn, it cannot have length exceeding that of Fn' Since this must be true for each n in N, we conclude that F, although uncountable, cannot have positive length. The Algebra. We assume that, relative to this ordering, every non-empty subset of N has a smallest element. Since many of the functions that we shall consider in subsequentsections are not defined for all points in the set A, we shall employ theword "function" much more than "mapping. The reader should interpret the ideas by drawing diagrams in Rand R z. The set E of evennatural numbers.
