Mathematical Institute SASA, an institutional member of the European Mathematical Society, is a scientific institute engaged in scientific research in the field of mathematics, mechanics and computer science. It was founded in 1946 as the first institute of the Serbian Academy of Sciences. The initiative for its formation came from three academics, two former members of the Mathematicians' Club, Milutin Milanković and Anton Bilimović, as well as then-President of the Academy, Alexander Belić. Their desire was to enable, in the aftermath of World War II, when '' libraries were empty and people were scattered through the numerous faculties where mathematics was taught '', to bring together people interested in the development of this scientific field. Since its founding, the Mathematical Institute has worked to raise and disseminate mathematical knowledge, which has been especially contributed by: The Library, established in 1946 as one of the first two mathematical libraries in the NRS territory in the aftermath of World War II, whose library stock today comprises about 15,000 books and hundreds of mathematical journals; Publishing, especially the continuation of the publication of the first international mathematical journal in Serbia - Publications de l'institut Mathématique; i Colloquiums and seminars for professional and wider audience. The SANU Mathematical Institute is today comprised of three scientific research departments - the Department of Mathematics, the Department of Mechanics, and the Departments of Computing and Applied Mathematics. In addition to researchers in Belgrade, the Institute has permanent staff in Novi Sad and Niš, as well as a large number of external associates in all university centers in Serbia. The Institute cooperates with numerous domestic and foreign institutions through participation in national and international projects
