Complex Analysis
This course will enable the students to -
- Introduce the fundamental ideas of the functions of complex variables, developing a clear understanding of the fundamental concepts of Complex Analysis such as analytic functions, complex integrals and a range of skills which will allow students to work effectively with the concepts.
- Identify and construct complex-differentiable functions.
