# Heinz Prüfer's publications

Today Prüfer's name is well-known by mathematicians yet he died at the age of 37 and he published only 9 papers and one book. We should note that several of the papers are long, being around 40 pages. One of the papers is in two parts. In addition he published solutions to two problems posed by George Pólya. The book, Projective Geometry (1935), was edited by G Fleddermann and G Köthe based on Prüfer's lecture notes at Münster University. With later editions of the book, this means that in total we are able to list 15 publications by Prüfer. We have added an English translation of the titles:
