Introduction to the fundamental group 

I regret no having seen this video before my Topology course got started, it's really eye-opening, thank you very much

Congratulations! You are an excellent professor. Your explanation is simple and correct. Really cool!

Excellent. Thanks !

Been looking for a nice calming math video.

Hey thanks for the video! I recently read Homotopy in Mendelson's Introduction to Topology, and this video helped in grasping the "math" in whole of the discussion and abstraction of paths and connectedness.

A literal life saver, thank you!

Great content😊

Very very helpful thank you

Awesome!

The fundamental group is a homotopy to the diagonal entries ( one fundamental group for each diagonal entry) in the subroutine call from-to matrix via Warshalls algorithm. The diagonal entry indicates if a subroutine ever calls itself(loops back to itself)!!! Clue: cf AI networks and how this applies!!!

Does this help with number theory?!! How can it be used?! For example, if I wanted to prove Fermat's Last theorem, how could it be used?

Thank you so much. Please support also the Homotopy type book if you are computer scientist

"it's called the Pochhammer contour"

What field is this? Topology? Group theory?

Thank you, unfortunately my professor is not the best explainer in the world ;)

c est quoi embedding en francais slp merci d avance
