Sequences, Continuity, and Limits

Chapter
Part of the Undergraduate Texts in Mathematics book series (UTM)

Abstract

In this chapter, we introduce the fundamental notions of continuity and limit of a real-valued function of two variables. As in ACICARA, the definitions as well as proofs of basic results will be given using sequences. There are, actually, two possible generalizations of real sequences that seem natural in the setting of two variables. First, functions defined on N with values in R2, and second, functions defined on N2 with values in R. As we shall see, for developing the notions of continuity and limit of a function of two variables, only the former is relevant, and it is studied in this chapter. The study of the latter will be taken up in Chapter 7.
