MWF 8:00-9:00 in BUCH A102
We will use the textbook
Fundamentals of Complex Analysis with Applications to Engineering and Science (Third Edition), by E. Saff and A. Snider.
Homework problem sets will be from Saff & Snider. You can also refer to the free online textbook
A First Course in Complex Analysis by Beck, Marchesi, Pixton and Sabalka.
1.The complex numbers. (Saff & Snider sections 1.1 - 1.6)
2.Analytic functions. (Saff & Snider sections 2.1 - 2.5)
3.Examples of Complex Functions. (Saff & Snider sections 3.1 - 3.3, 3.5)
4.Complex Integration. (Saff & Snider sections 4.1 - 4.7)
5.Taylor and Laurent Series (Saff & Snider sections 5.1 - 5.6)
6.The residue theorem (Saff & Snider sections 6.1 - 6.4)
There will be weekly homework assignments, usually due on Mondays. You will be required to upload files in pdf format (either scanned handwritten solutions, or prepared with a typesetting program such as LaTeX) on the course canvas page. A selection of problems will be graded. Late homework will not be accepted, even if you have a good excuse. To compensate, I will drop the lowest homework score. Even if you miss the deadline, its a good idea to do the problems, since this is the best way to prepare for the tests and exam. You are welcome to discuss the homework problems with your friends, but are expected to hand in your own work.
There will be two midterm exams on October 11 and November 8 in class and a final exam during the exam period.
The following weightings will be used in computing your final grade:
|Homework (lowest score dropped):||10%|
|Midterms:||2 x 20%|
If you miss a test for a legitimate reason, please fill out an academic request form and bring it to me. The weight of the test will be transfered onto the final exam.
To hand in homework, upload a pdf file on the canvas page before the due date.

UBC provides resources to support student learning and to maintain healthy lifestyles but recognizes that sometimes crises arise and so there are additional resources to access including those for survivors of sexual violence. UBC values respect for the person and ideas of all members of the academic community. Harassment and discrimination are not tolerated nor is suppression of academic freedom. UBC provides appropriate accommodation for students with disabilities and for religious, spiritual and cultural observances. UBC values academic honesty and students ae expected to acknowledge the ideas generated by others and to uphold the highest academic standards in all of their actions. Details of the policies and how to access support are available here.
