Vorlesungen uber Zahlentheorie - Peter Gustav Lejeune Dirichlet - Bog

These lectures by Dirichlet (1805-59) were published posthumously by his former colleague Richard Dedekind. They include Dirichlet's famous proofs of the class number theorem for binary quadratic forms and the existence of an infinity of primes in every appropriate arithmetical progression. This reissue is of the third, expanded edition of 1879.
