# Topology and Functional Analysis Notes for BS/MSc

Topology and functional analysis are two important branches of mathematics that deal with the study of abstract spaces, continuity, and functional relationships. While they are distinct areas of mathematics. They share some connections. They are often used in various mathematical and scientific disciplines.
