Hans Hefer (born on 27 February 1907[1] and died on 22 November 1941, Eastern Front[2]) was a German mathematician who worked on several complex variables. Hefer's lemma or Hefer's theorem bear his name.[3][4]
Life
[edit | edit source]There is not sufficient documentation regarding the life of Hans Hefer. Hefer is known to have earned a Ph.D. at the University of Münster in 1941, supervised by Heinrich Behnke.[2][5]
In a posthumous publication made by Karl Stein and Heinrich Benke with Hefer's name in Mathematische Annalen in 1950/51, it was written in a footnote that the author had fallen in the East and the article is an excerpt from his dissertation which he defended in 1940.[6] It was also added there that Since 1941, papers by K. Oka and H. Cartan have appeared that contain Hefer's result but use different proofs.
