Advanced Complex Analysis

 (Theory)

 

 

 

 

 

The students will be able to –

 

CO86: Determine whether a sequence of analytic functions converges uniformly on compact sets.

CO87: Acquire knowledge about different types of functions viz. analytic, entire and meromorphic functions occur in complex analysis along with their properties

CO88: Describe conformal mappings between various plane regions.

CO89: Utilize the concepts of complex analysis to specific research problems in mathematics or other fields.

CO90: Enhance and develop the ability of using the language of mathematics in analyzing the real-world problems of sciences and engineering.

CO91: Express some functions as infinite series or products

CO92: 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.
