  • Syllabus (tentative: the list below will grow as the semester progresses )

    Your lecture notes will cover all the material (except for those results assigned for self-study) in the syllabus. The occasional chapter references below are to a more extensive treatment of the topic in question and indicate the primary source of the material presented in the lectures.

    The natural numbers, Peano's axioms, mathematical induction, Peano arithmetic

    Aspects of the theory of sets, the axioms of specification and union, De Morgan's laws

    Two-fold cartesian products, relations and functions, equivalence relations

    The integers: the definition/construction of the set of integers and integer arithmetic, ordering the integers

    The rational numbers, fields, ordered fields and the "usual order" on the rationals

    The least upper bound property, the definition/meaning of real line

    (The treatment of the above topics follows, although selectively, that of Chapters 1–4 of Tao's Analysis 1)

    Dedekind cuts, construction of the real line (Chapter 1: Appendix of Rudin's Principles)

    The Archimedean property of the real line

    Countable and uncountable sets

    Metric spaces, open and closed sets in metric spaces and associated concepts

    Closure and interior of a set in a metric space, and their relative analogues

    Compact metric spaces (Chapter 2 of Rudin's Principles)

    The characterisation of compact subsets of Euclidean spaces

    Properties of compact subsets of a metric space, the Cantor set

    Sequences and convergence

    Cauchy sequences, the definition of completeness, completeness of the real line

    Topics listed up to this point comprise the syllabus of the mid-term examination. They will also be a part of the syllabus of the final examination.

    Sufficient conditions for completeness

    Subsequences, subsequential limits

    The extended real number system, limits at infinity, upper and lower limits (i.e., limsup and liminf)

    The limits of special sequences (the section Some Special Sequences in Chapter 3 of Rudin's Principles)

    Infinite series and their convergence, criteria for convergence

    Convergence tests for non-negative series, criterion for summability of the series of pth powers

    Absolute convergence, the Ratio and Root Tests, convergence tests for non-negative series as tests for absolute convergence, conditional convergence

    The limit of a function: various equivalent definitions, the algebra of limits

    Continuous functions

    Continuity and compactness, attainment of extreme values, uniform continuity

    Connectedness, the characterisation of all connected subsets of the real line

    Continuity and connectedness, the intermediate-value theorem, and applications

    Differentition in one variable

    The chain rule for differentiation in one variable

    Geometric interpretations of the derivative, the relation between critical points and points of local maximum/minimum

    Rolle's theorem, Lagrange's mean value theorem and its applications

    Higher-order derivatives, Taylor's theorem

    Integration: motivation, the Riemann integral, and a characterisation of Riemann integrability

    Riemann integrability of continuous functions, functions with discontinuities

    (The treatment of the above topics in the theory of the Riemann integral is that of Chapter 6 of Rudin's Principles, with the following major difference: the gauge α in Rudin's discussion of the Riemann–Stieltjes integral is just id[a, b] for this course.)

    The first and second Fundamental Theorems of Calculus

    Techinques of integration: the change-of-variable formulas for the Riemann integral, integration by parts

    Definition and properties of the logarithm

    Sequences of functions, examples and motivations for uniform convergence

    Uniform convergence and Riemann integration

    The sup-metric, the relationship between uniform convergence and convergence relative to the sup-metric

    The space Cb(X;Y) and its completeness (when Y is complete)

    Equicontinuity, compact sets in C(K;Rn): the Arzela–Ascoli Theorem (proof not included)

    The Weierstrass approximation theorem (Chapter 7 of Rudin's Principles. Note: we omit the Stone–Weierstrass theorems.)
