Qualifying Exam in Applied Mathematics - Part A
Three courses in real and complex analysis are recommended for students preparing for Part A:
  • Math 645: Analysis I
  • Math 745: Analysis II
  • Math 656: Complex Variables I  

Material Covered 

The real analysis portion of the exam focuses on material covered in the two one-semester courses `Analysis I and Analysis II' (Math 645 and Math 745) and in chapters three through eleven of the second edition of `Mathematical Analysis' by T.M. Apostol. For example, students should be familiar with the theory of the Riemann integral (but not necessarily the Riemann-Stieltjes integral), the Fundamental Theorem of Calculus, and the Lesbesgue criterion for Riemann integrability. Another good reference for the Riemann integral is `Calculus' by M. Spivak.

The complex analysis portion of the exam focuses on material covered in the one-semester course Complex Variables I (Math 656). This corresponds approximately to chapters 1 through 5 of `Complex Variables' by Ablowitz and Fokas or chapters 1 through 4 of `Functions of a Complex Variable' by Carrier, Krook and Pearson.  

Students should note that the exam emphasizes an ability to apply the material described in the outline.
