Lecture Notes of the Courses I offer and Lecture Notes from the talks I have given

Some lecture notes of my courses and talks delivered (will be updated constantly as time evolves and new notes will be added in future)

I found that several of my course notes were roaming in different google drives maintained by students and unofficially used by many students for their courses, so I decided to make it official !! These notes will be evolving (I mean, not a constant with respect to time) as and when I take new topics etc.
