In number theory, Dirichlet's theorem, also called the Dirichlet prime number theorem, states that for any two positive coprime integers a and d, there are infinitely many primes of the form a + nd, w
Johann Peter Gustav Lejeune Dirichlet
Johann Peter Gustav Lejeune Dirichlet was a German mathematician. In number theory, he proved special cases of Fermat's Last Theorem and created analytic number theory. In analysis, he advanced the th
Dirichlet's theorem on arithmetic progressions
…evenly distributed (asymptotically) among the congruence classes modulo d containing a coprime to d. The theorem is named after the German mathematician Peter Gustav Lejeune Dirichlet, who proved it in 1837. The primes of the form 4n + 3 are (sequence A002145 in the OEIS…
