In this video we motivate and define the concept of a topological space.

you are the greatest teacher ever at linking intuition with rigorous definitions. I can truly see WHY people defined a concept in a certain way. That is very good because it is the most lacking part of the book Topology Without Tears!

I just started on this, but I have to agree with other commenters that this lecturer breaks the taboo that so many books on math seem to have on asking "Why are we doing this?", the question that is the key to all motivation. Thanks!!

This video is awesome! The excitement you have while explaining the stuff really inspires me. I know I will not need this stuff for the rest of my life, but you are triggering some kind of intereset in this topic. Thanks to people like you, students can understand such abstract math!

I really enjoyed your playlist on group theory so this is very welcomed. However, I cannot find any playlist of yours named Topology. What videos are supposed to be included in the playlist that you are referring to in this video?

Tks for your videos so much! The best explanation about topological space I've ever heard. This motivates me. I'm studying about measure theory and I don't know intuitive interplay between topology and measure theory. What is the role of topology in measure theory?

Around 23-24 minute. If we intersect two subsets, and we get an empty subset, does this satisfy the intersection condition for topology? Are these two subsets then in the topology?

I think you've got the if and then mixed up. If two subsets are in tau then their intersection is also in tau. If their intersection is empty then the empty set is already there in tau, so the only real thing to look for is every non-empty intersection must be in tau. What you are doing is reversing the if and then- "if the intersection of two subsets is in tau then both the subsets are in tau"- which is not what the axiom says. I hope I've made myself clear.

@joshuaokoro27813 жыл бұрын
It is not thta pure mathematicians insist that empty set and the whole set need to be in the topological space, it because of the unions and intersections. I hope you understand.

You should get paid for this
is it possible ??Toplogy define on empty set?
Why are you repeating yourself
