Qualification Goals

Students will

  • Understand how complex-analytic methods enable them to solve problems in real analysis,
  • have deepened their understanding of elementary functions through the complex point of view,
  • know connections of methods of geometry, algebra, and calculus, as well as topology and number theory, and have further developed their mathematical understanding as a result,
  • have learned methods and skills central to applications in computer science (e.g., coding theory), physics (e.g., quantum theory), and engineering (e.g., electrical engineering),
  • have practiced mathematical ways of working (developing mathematical intuition and its formal justification, training the ability to abstract, reasoning),
  • have improved their oral communication skills in exercises by practicing free speech in front of an audience and in discussion.
