Sums of two squares are strongly biased towards quadratic residues
17 mars 2022 @ 14:30 – 15:30 – Chebyshev famously observed empirically that more often than not, there are more primes of the form 3 mod 4 up to x than primes of the form 1 mod 4. This was confirmed theoretically much later by Rubinstein and Sarnak in a logarithmic density sense. Our understanding of this is conditional on the generalized Riemann […]
