Wolfgang Krull

Wolfgang Krull ( born August 26, 1899 in Baden -Baden, † April 12, 1971 in Bonn ) was a German mathematician. His focus was on the commutative algebra.

Krull was the son of a dentist in Baden -Baden and studied from 1919 in Freiburg im Breisgau and Rostock, 1920/21 in Göttingen, where he was a student of Felix Klein, but was particularly marked by the collaboration with Emmy Noether. In 1922 he received his doctorate in Freiburg About Begleitmatrizen and elementary divisor theory and became associate professor in 1926. In 1928 he went as professor to Erlangen. In 1939, he was the successor of Otto Toeplitz in Bonn, who was on leave in 1935 because of the racial laws of the Nazis. In Bonn he remained until the end of his career, interrupted in World War II by the meteorological service in the Navy.

Krull made ​​a significant contribution to the development of modern ring theory.

After the Krull Krull dimension (1928 ), Krull topology, Krull reviews, Krull rings, the average rate of Krull and Krull's principal ideal theorem are named. With the Krull topology can the law of Galois theory extended to infinite field extensions.

He was married in 1929 and had two daughters.

His doctoral include Wilfried Brauer, Manfred Breuer and Jürgen Neukirch.
