 Lecture Topics 1 Basic Logic, Peano Axioms, mathematical induction. 2 Mathematical induction, equivalence relations. 3 Construction of the rational numbers. Fields. 4 Rational numbers form an ordered field. 5 Upper and lower bounds, the least upper bound and the greatest lower bound, the least upper bound property. 6 The Archimedean property and consequences. 7 Construction of the real numbers. 8 "Uniqueness" of an ordered field with the least upper bound property. 9 Sequences: bounded, monotonic, convergent. Examples. 10 Limit Theorems. Sequences diverging to ±∞. 11 The Cauchy criterion. 12 The limsup and liminf of a sequence. 13 The limsup and liminf of a sequence. 14 Series: convergent, absolutely convergent. The Cauchy criterion, the comparison and root tests. 15 The ratio test, the Abel, Leibnitz, and dyadic criterions. 16 Rearrangements. 17 Functions: domain, range, image, preimage, injective, surjective, bijective, inverse. 18 Cardinality of a set: finite, infinite, countable, at most countable, uncountable. Examples. 19 A set is infinite if and only if it is equipotent to one of its proper subsets. The Schroder-Bernstein theorem. 20 A countable union of countable sets is countable. Finite and countable cartesian products of countable sets. Examples. 21 Metric spaces, examples, the Holder and Minkowski inequalities. 22 Interior, adherent, isolated, and accumulation points. Open and closed sets and their properties. 23 Subspaces of a metric space. 24 Complete metric spaces: definition and characterization. 25 Complete metric spaces: examples. Baire's category theorem. 26 Separated sets and properties. 27 Connected sets: equivalent definitions. 28 Connected subsets of the real line. Decomposition of a set into its connected components.
