Mathematicians Of The Day

27th July

On this day in 1837, Lejeune Dirichlet presented his first analytic number theory paper at a meeting of the Berlin Academy of Sciences. He proved the fundamental theorem that bears his name: Every arithmetical sequence an + b, n = 0, 1, 2, ... of integers, where a and b are relatively prime, contains infinitely many primes.
