## COURSE OBJECTIVES

The course is designed to review fundamental topics in functional analysis. It is necessary to study the Banach contraction principle and its various generalizations. The power of abstraction in mathematics can be realize from the concept of metric spaces in functional analysis. We will be looking at various abstract spaces and their properties and discuss some well known fixed point theorems in such spaces.

## COURSE LEARNING OUTCOMES (CLO)
