Shimshon Amitsur

Published

01In brief

Shimshon Abraham Amitsur (1921–1994) was a mathematician whose work included a 1972 result in associative algebra. In 1972, he settled the question of whether all finite-dimensional central division algebras are crossed products; he had earlier received the 1953 Israel Prize in exact sciences.

02Early Life

Shimshon Abraham Amitsur was born in 1921 and died in 1994.[1] The biographical entry records his name in Hebrew as שמשון אברהם עמיצור, but provides no further details about his upbringing, education, or early career.[1]

03Career

Amitsur received the Israel Prize in 1953 in the exact sciences discipline.[3] The published list records him alongside Jacob Levitzki, who was also recognized in exact sciences that year.[3]

In 1972, Amitsur settled the question of whether all finite-dimensional central division algebras are crossed products. The question had been a notable focus of Abraham Adrian Albert's work on associative algebras.[2]

04Legacy

Amitsur’s 1972 result was published as “On Central Division Algebras” in the Israel Journal of Mathematics, volume 12, pages 408–420.[2] The result resolved the crossed-product question that had been a notable focus of Albert’s research in associative algebras.[2]
