General Information 
Course Overview. This is an advanced undergraduate course covering fundamental aspects of functions in one complex variable. We start with the definition and properties of complex numbers including their geometric interpretation. Then we define the notion of complex differentiable function (aka holomorphic) in one complex variable and study some basic examples. We continue with Cauchy integral formula and derive some striking properties of holomorphic functions such as analyticity. We also study isolated singular points of holomorphic functions (Laurent series, residues, Cauchy's Residue formula). Then we apply residues to evaluation of improper integrals. We also cover such topics as harmonic functions and iterated maps (i.e. fractals). Why would you want to take this course? Complex numbers may seem at first to be a difficult abstraction, but in fact they provide a mathematically simple framework which has many beautiful and useful properties. There are many surprising relationships which turn hard questions (calculating integrals, counting roots of a polynomial in a region) into easy ones. There is geometry  which means pictures!  underlying many of the ideas. Moreover, the theory of complex variables proves useful to other fields of mathematics (like number theory, for example) and there are countless applications to physics and engineering. Indeed, this course is a highlight of the undergraduate mathematics curriculum.

Grades. Your grade will be based on two hourly exams, periodic quizzes, the daily homework, participation, a Mathematica project, and a final exam. Each will be weighted as follows.


Daily Homework. As with any math class, homework is the most important aspect of the course. Homework exercises will be collected and graded regularly (typically about 1 assignment per week.) Your homework must be legible, with problem number and final answer clearly indicated. Explanations should be written in complete sentences. Random math expressions floating in space will receive no credit.


Exams. There will be two hourly exams and a comprehensive final exam. Their dates are given below.
Note: the final exam will be inclass and cumulative. 

Academic Honesty. In general, the rules set forth in the 20072008 Course of Study apply. Presenting the work of others as your own is strictly prohibited. In the case of homework, you may collaborate with others in discussing how a problem may be solved, but your writeup must be your own. If you submit work that contains the ideas or words of someone else, then you must provide proper citation. Assistance can not be given nor received (other than by the instructor) on any quiz, or exam associated with this course, except where explicitly allowed by the instructor. In the case of a group assignment, all members of the group should contribute equally to writing the final product. And every member of the group is responsible for the content of the entire paper, not just the section(s) that are written by that person. Don't put your name on a paper written by others. For further information, consult your instructor.  
Learning Disabilities. If you have a disability which requires an accommodation in this class, please feel free to discuss your concerns with me, but you should also consult Ms. Erin Salva, (Coordinator of Disability Services; Office of the Dean for Academic Advising, PBX 5453) as soon as possible. Ms. Salva (in consultation with the L.E.A.R.N. committee) has the authority and the expertise to decide on the accommodations that are proper for your disability. Though I am happy to help you in any way I can, I cannot make any accommodations for learning (or other) disabilities without proper authorization from Ms. Salva.
