    Very nice lecture Sir. I was reading open mapping theorem in functional analysis where in its proof, we use Baire category theorem. So I was looking concept behind baire theorem. And this lecture ends all my search. I got clear concept of baire th. Thanks a lot sir for this video.

    Each and every moment of this lecture is precious. I am totally amazed. I was so absorbed in it that I did not notice how 57:19 min passed. 👌👌👌👌👌👏👏🙏🙏🙏🙏🙏🙏

    Respected Sir,
    Very lucky to get a chance to learn.
    Two kinds of training I always enjoy in every lecture:
    1. How to learn,
    2. How to teach.

    Very good lecture....Most of the lectures speak about how to go from step n-1 to step n.....very few gives us intuition...Your lecture give students a very good amount of intuitive idea....Through your lectures we learn to enjoy Mathematics...Thank you for all your efforts...Eagerly waiting for the next series of Lectures

      There are other series of lectures: Real Numbers, Sequences, Continuity, Uniform Continuity, Group Actions,.. Start from the beginning even if you are very confident. Watch any video not more than 20-30 minutes, stop at a P-R-P. Resume it after sometime. Or, use them as bedtime watches than the soap-operas/TV serials. Do not strive to remember, be with the flow of thinking, think along with me. You will be amazed how this transforms you in about a month's time.

    Thank you sir for taking into different world after long time especially during this lockdown. I have completely involved in the proof and not felt like in watching video. Beautifully constructed the proof.

    Thank you so much sir..I request you to upload videos on this theorem..I am very much excited after seeing your videos..you also told me to read your books..I read all the results from your books..I never think about geometry of metric space..but after seeing the proof of baire category theorem from your books by diagram..no words to express my excitedness...I think you are one of the best mathematician in the world...

    Thank you sir...you provide the idea why should we modify open balls to closed balls in the proof...that's was awesome...it'll be better if you share some lectures on elementary topics of algebraic topology...

    Thank you so much sir. It was a long time wish to learn this theorem properly and now it has been fulfilled. I request you for a separate lecture video on logic sir. (Similar to the Foundation course in MTTS for Level O).

    Suppose if there exist such a d then Q cannot be written as a countable union of nowhere dence set but that is not true because Q is countable and it can be written as union of singletons (singletons are nowhere dence in usual metric) sir is this argument correct?
