Introduction to Complex Analysis
Introduction to Complex Analysis. Instructor: Prof. William Kinney, Math and Computer Science, Bethel University. Complex analysis involves extending the real number system by introducing an "imaginary unit." It is an extremely beautiful subject with lots of unexpected treasures and that, perhaps surprisingly, also has real-life applications. You are encouraged to explore some real-life applications in your project. Main topics dealt with in this course include: complex arithmetic and coordinate geometry; complex functions (especially as "mappings"); derivatives of complex functions and their interpretations; integrals of complex functions and their interpretations; infinite series of complex numbers and complex variables; residue theory and applications to evaluation of definite integrals; conformal mapping and Mobius transformations.
