    Yayyy, good to see a new upload in the more advanced math series :))

    Saw it the first time in stat mech and thought yeah I guess it makes sense that the delta distribution should be the derivative of the heavyside but this is of course much more lucid

    How many more videos are you planning to make for distributions!? Thank you for this video, very helpful again:)

      I planned around 20 videos.

      @@brightsideofmaths Okay, cool. I really like your teaching/video style. I was introduced to distribution theory during my undergraduate and found it really interesting. Now I’m taking it as part of my masters degree and unfortunately it is taught in a completely different way than how I was introduced to it and it doesn’t feel even remotely as engaging. But your videos are in line with how I was introduced to the subject so I’m super happy that I found them. I’ll just hope that as many more videos as possible get released before my exam in August 😅

    Hello !
    First the serie is insane thank you a lot !
    I have a question : during the serie and in this episode also you define property of distribution with nice function with good property then you apply this properties to all function.
    Exemple: To define the derivative of a function in this video you use f a C1 function but then you use the derivative define previously for all the function
    If you can do that, why can you ?
    Thank you for reading and for the videos :))

      Hello and thank you very much for your support! I don't get your question, maybe. We have the space of test functions which consists of C-infinity functions.All this functions are very nice and that's the reason the definitions work.

      ​@@brightsideofmaths Excuse me that was not very clear ^^
      In this video you show that , but you show that for a regular distribution, so why you can use this definition on the dirac distribution who is not a regular distribution ? I miss something ?

    • @brightsideofmaths
      @brightsideofmaths  ปีที่แล้ว +1

      It's simply the definition :)

    Hello, thanks for this series. They really accelerated my understanding of distributions. I have a question regarding the definition of Distributional derivatives. @5.04 you say about the motivation for the definition of Distributional derivatives. But I am not able to find the relation of the definition with the previous discussion . What is bothering me is, since T is a functional, it's derivative should also be taken like any functional ( en.wikipedia.org/wiki/Functional_derivative#Functional_derivative ), but instead what is done here is the distribution of derivative of it's function. To conclude I don't know how T'f = Tf'

    • @brightsideofmaths
      @brightsideofmaths  ปีที่แล้ว +1

      Simply speaking: we define the distributional derivative and not the functional derivative.
