Welcome to Math 417! This course is an introduction to Complex Analysis. Complex Analysis is one of the great subjects of modern mathematics and an invaluable tool in physics and engineering. In this course we will explore the basic properties of complex analytic functions and conformal maps.

** Lecturer: ** Izzet Coskun, icoskun@uic.edu

** Time: ** 11:00-11:50 MWF

** Dropin hours: ** M 9:00-11:00

** Venue: ** Taft Hall 208

** Text book: ** Complex variables and applications by J.W. Brown and R.V.Churchill, McGraw Hill, 2004, Seventh Edition. All page numbers below refer to this book. You may use a different edition or an equivalent text book.

** Prerequisites: ** A solid background in basic analysis including the concepts of limits, continuity, differentiability, Riemann integrals and line integrals. I will assume that you are comfortable with writing proofs.

** Homework: ** There will be weekly homework. The homework
is due on Mondays at the beginning of class. Late homework will not
be accepted. You are allowed to discuss problems; however, the
write-up must be your own and should reflect your own understanding of
the problem. Three of the homeworks will be special (Midterm I, II and Final). These will be slighly longer, cumulative and you will be required to do on your own.

** Grading: ** Your grade will be entirely based on the homework. The three longer homework sets (Midterms I,II and Final) will each account for 20% of your grade. The regular homework exercises will account for 40% total. In addition, you can write an optional 7-10 page paper on the applications of complex analysis to your field of specialty. A well-written paper will increase your grade by one letter grade.

** Additional references: ** There are many excellent text books in Complex Analysis. You might want to refer to them for more information or a different point of view. Some of my favorites are:
