Objective: 
This course will enable the students to -
  1. 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.  
  2. Identify and construct complex-differentiable functions

The students will be able to –

 

CO74: Demonstrate the remarkable properties of complex variable  functions, which are not the features of their real analogues

CO75: Acquire knowledge about different types of functions viz. analytic, entire and meromorphic functions occur in complex analysis along with their properties

CO76: Apply the knowledge of complex analysis in diverse fields related to mathematics.

CO77: Utilize the concepts of complex analysis to specific research problems in mathematics or other fields.

CO78: Enhance and develop the ability of using the language of mathematics in analyzing the real-world problems of sciences and engineering.

CO79: Learn the significance of differentiability of complex functions leading to the understanding of Cauchy−Riemann equations.

CO80: Expand some simple functions as their Taylor and Laurent series, classify the nature of singularities, find residues and apply Cauchy Residue theorem to evaluate integrals.
