Analysis Qualifying Exams

Syllabus Topics

This exam will test your working knowledge of basic real, complex and functional analysis. You will be required to demonstrate an ability to use standard results and techniques to solve problems, including special cases of standard theorems which do not require long arguments.

We will not emphasize the memorization of statements of theorems nor of long proofs of standard theorems.

The student is urged to work on the problems in the relevant sections and chapters in the reference books.

Syllabus (updated Fall 2020).
There will typically be 12 problems, 7 from real analysis and 5 from complex analysis. Students must designate 10 to be graded.

Real Analysis

  • Abstract measure spaces and construction of measures.
  • Measurable functions and general theory of integration.
  • Integral Convergence Theorems (Fatou, Monotone, Dominated, Vitali).
  • Modes of convergence: convergence a.e.; convergence in measure and convergence in the mean and how they are related to each other, Egorov's Theorem, Luzin's Theorem.
  • Absolute continuity and the Radon-Nikodym Theorem.
  • Product Measures and Fubini-Tonelli Theorem
  • Lebesgue Differentiation Theorem; Comparison of Riemann and Lebesgue integrals; Bounded Variation etc.
  • Lp spaces with 1≤p≤∞, Hölder inequality, Minkowski inequality, Jensen's inequality, convergence in Lp, completeness of spaces, dense sets of Lp( a,b) (1≤p<∞).
