Please read Course outlines
Very important: prerequisites (class in Complex variables and class in Partial differential Equations) are required. These are prerequisites and not corequisites. And 2nd year classes (Multivariable Calculus and Ordinary Differential Equations) which are prerequisites for Complex variables and PDE are also required.
Also, the attendance of lectures is very strongly advised. 20% of the grade are for Class Participation. Active participation is strongly encouraged.
