Shimshon Amitsur

Shimshon Avraham Amitsur was an Israeli mathematician. A leading figure in twentieth-century noncommutative algebra, he is best known for his wide-ranging contributions to ring theory, including the theory of rings with polynomial identities (PI-rings), division algebras, the general theory of radicals, and the Amitsur complex in descent theory. His collected works, published in two volumes by the American Mathematical Society in 2001, are organized into four broad areas: general ring theory, structure theory of PI-rings, combinatorial PI-theory, and division algebras.
