    Not sure why it's so hard to find an explanation of this online, but so glad I finally found this amazing explanation. Thanks!

    Thank you so much. It was really very helpful and I must say the view behind you was the icing on the cake. (Imagining myself being there and studying mathematics.)

    Thanks for this! Really great, never thought about twisting the loop to glue the remaining points. This really put it together for me!!

    I understand how there should exist a bijection between RP1 and S1, but how would you formally define a function to demonstrate it? Thank you!

    Great video! Thanks! Where can I find a similar analysis for CP^1?

    • @MathForLife
      @MathForLife  3 года назад +2

      Thanks! I don't know,, you can try to find this stuff on other channels. I will cover RP^2 first and then move to CP^1.

    After gluing antipodal point of circle we should get RP1 that is some line passing through the origin? Which is definition of RP*2

    say a point C, is removed i.e. M= ℝ𝑃²-{C}
    “A pair of straight lines in M passing through the point C have no intersection in M, neither finite or infinite”. How does this statement sound in ℝ² terms?

    • @MathForLife
      @MathForLife  3 года назад

      I am not completely sure what the question is asking to be honest. Is this from a book?

      @@MathForLife it is actually from a homework that i find difficulty to understand

    Hello,
    Solving a linear system of two equations in two unknows is interpreted as finding the point(s) of intersection between two straight lines in the real plane ℝ², with three possible outcomes: no intersection, one intersection point, and a whole line. What are the corresponding interpretation and outcomes in ℝP²?

    • @MathForLife
      @MathForLife  3 года назад

      All lines that have the same slope will correspond to a single point in RP^2.

  • @celinebaddour9797

    In the real plane ℝ², one can define the a relation for three collinear points (as a point is between the two others). Is this relation can defined for three collinear points in ℝP²?

    • @MathForLife
      @MathForLife  3 года назад

      About what relation are you talking about?

    • @celinebaddour9797
      @celinebaddour9797 3 года назад

      I mean if we have three collinear points in RP² can we see them as a point is between the two others?

    i feel this one, you didnt prepare well.

    • @MathForLife

      I record most of my videos without preparation i.e. with one take. However, I prepare topology series.
