REAL AND COMPLEX ANALYSIS
Qualifying Examination Syllabus
The analysis examination (3 hours) covers topics from both real and complex
analysis.
It is expected that the student has mastered the basic principles of analysis
of real functions of one and several variables. It includes, among other
topics, knowledge of the Riemann integral, the differential, the Jacobian
matrix, the implicit function theorem, and Stokes' theorem. In addition, the
following outlined topics from the theory of functions of a real variable, and
the theory of functions of a complex variable should be mastered.
