    Inner products and Hilbert spaces? More like "Interesting lectures and hearty specifics!" Thanks again for making all these incredible videos with such nice examples and clear explanations.

    Hi, are you going to talk more about the case (c) C([0,1], IF) in the future videos? This case seems to be very important for many applications. Thanks!

    At around 1:00 , why is it the complex conjugate for x_i ? And what part of mathematics studies this?

    • @brightsideofmaths
      @brightsideofmaths  3 ปีที่แล้ว +3

      Complex conjugate is needed such that sqrt() defined a norm. A nice application for this inner product might be quantum mechanics.

    Are Fourier series cauchy sequences in the continuous function space we defined? If so then the fact that Fourier transforms can approximate discontinuous functions to an arbitrary close degree is because the continuous functions aren't a Hilbert space

      Very nice :)

    • @wesleyrm
      @wesleyrm ปีที่แล้ว

      By "because" you meant "the cause"? As in, you provided an example of a Cauchy Sequence converging to a discontinuous function. So that would be "the cause" of continuous functions armed with the usual norm not being complete: we have Cauchy Sequences not converging to an element in the space of continuous functions.

    I cannot even stop watching your videos my friend lol. A very small suggestion and I am not sure if it would be too time-consuming. Some videos' subtitles are closed and some of them are wrong (e.g., you are speaking English but the only option for the subtitle is German -> English, and the recognition of German is apparently not accurate cuz you are saying English). Adding subtitles by yourself might be too labor-intensive but could you open the Auto-generate (English) for those missing ones? Thank you!

    • @brightsideofmaths

      But maybe you can tell me which videos have the problem. Then I will put subtitles to it!

    I miss the quizzes and I also noted that you are start using complex numbers I haven't take the complex course yet do you believe that I could finish this one (I mean understanding properly) without taking that one before? O would be better to go for the complex one right now? Thanks

    • @brightsideofmaths
      @brightsideofmaths  ปีที่แล้ว +1

      Complex numbers don't change so much. However, it is always good to know how they work. You can check my course about them, which is also short: tbsom.de/courses/start_learning_complex/overview/
