G.Lejeune Dirichlet's Werke
Kronecker, L. / Fuchs, L.
Dirichlet (1805-1859) is well known for his significant contributions to several branches of mathematics. In analysis, he is remembered for his work in potential theory, especially his study of harmonic functions with prescribed boundary values, now known as the Dirichlet problem. This work features two volumes of "Dirichlet's Collected Works".
