Perturbation techniques with the emphasis on developing asymptotic solutions: approximation of integrals Laplace's method, stationary phase method, method of steepest descent , regular perturbations of ODEs, singular perturbations to ODEs matched asymptotic expansions, WKB approximation , multiple scale methods.

For most equations that arise in modeling applications it is unlikely that exact solutions can be found. Even convergent series approximations are often not available, or they are of limited use if they converge very slowly. Instead, asymptotic expansions can yield good approximations. They are typically divergent if summed to infinity but a few terms can often give excellent and well defined approximations.

This course will introduce the basic ideas and show how they can be applied to algebraic and differential equations, and to the evaluation of integrals. Usually some parameter or some coordinate value is small or large , which leads to an expansion of a solution in this parameter.

These perturbation expansions can be well behaved regular if the perturbation parameter goes to zero, or they can become singular. Most emphasis is placed on the latter, singular perturbations. Practical problems are used as illustrations. These techniques are especially useful when accurate numerical solutions are hard, or impossible, to obtain.

In other words, ordinary differential equations and complex variables. You will have a choice of proposing your own project or taking one of the projects offered by the instructor. Projects should be chosen by Wed, Feb 28th. Projects are due on Wed, April 25th. You should consult the instructor regarding your choice of own project as soon as possible and not later than Wed, Feb 21st.

Make-ups for missed quizzes and exams will only be allowed for a university approved excuse in writing. Wherever possible, students should inform the instructor before an exam or quiz is missed. Consistent with University Student Rules, students are required to notify the instructor by the end of the next working day after missing an exam or quiz.

Otherwise, they forfeit their rights to a make-up. Sometimes the instructor might make a mistake grading your work. If you feel that this has happened, you have one week since the graded work was handed back to you to talk to the instructor. If a mistake is confirmed, the grade will be changed.

No complaints after that deadline will be considered. Copying work done by others, either in-class or out of class, is an act of scholastic dishonesty and will be prosecuted to the full extent allowed by University policy. Collaboration on assignments, either in-class or out-of-class, is forbidden unless permission to do so is granted by your instructor. For more information on university policies regarding scholastic dishonesty, see University Student Rules.

The Americans with Disabilities Act ADA is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities.
