    Dirichlet made deep contributions to mathematics, especially in number theory by his work on primes in arithmetic progressions, introducing Characters and L-functions, Class number formula, Units in number fields, Divisor problem, Diophantine approximations, reciprocity laws, special cases of Fermat’s last theorem. In analysis he introduced important ideas like Dirichlet Kernel (Fourier convergence), Dirichlet boundary conditions, principle in PDE.

    Life and Work of Dirichlet

    Proof of Fermat’s Last Theorem for

    Primes in a given arithmetic progression (1837).

    Main ideas: Introduces the Dirichlet characters (He does it explicitly using primitive roots modulo and root of unity, not abstractly as characters of the group , which helps to detect primes in arithmetic progressions and access the sums in terms of the logarithms of Dirichlet L-functions That reduces the problem to showing non-vanishing of for non-trivial characters. For non-real characters occur in pai

    Johann Peter Gustav Lejeune Dirichlet German was a German mathematician who made deep contributions to number theory including creating the field of analytic number theory, and to the theory of Fourier series and other topics in mathematical analysis; he is credited with being one of the first mathematicians to give the modern formal definition of a function.

    Although his surname is Lejeune Dirichlet, he is commonly referred to as just Dirichlet, in particular for results named after him.

    Biography

    Early life 1805–1822

    Gustav Lejeune Dirichlet was born on 13 February 1805 in Düren, a town on the left bank of the Rhine which at the time was part of the First French Empire, reverting to Prussia after the Congress of Vienna in 1815. His father Johann Arnold Lejeune Dirichlet was the postmaster, merchant, and city councilor. His paternal grandfather had come to Düren from Richelette or more likely Richelle, a small community 5 km 3 miles north east of Liège in Belgium, from w
