Number Theory | Infinitely many primes of the form 3n+1.

In our third and final video regarding the infinitude of primes of a certain form we us the notion of quadratic residues and quadratic reciprocity to prove there are infinitely many primes of the form 3n+1.

I never knew quadratic reciprocity can be used to prove this. Very cool! Thank you!

Was searching for this type of Proof dint find it anywhere else thanks

Professor Penn, thank you for another great video on Infinitely many primes of the form 3n+1. These videos/lecture continues to be very theoretical in Number Theory.
