Karl F. Sundman Explained

Karl Frithiof Sundman (28 October 1873, in Kaskinen – 28 September 1949, in Helsinki) was a Finnish mathematician^[1] who used analytic methods to prove the existence of a convergent infinite series solution to the three-body problem in two papers published in 1907^[2] and 1909.^[3] His results gained fame when they were reproduced in Acta Mathematica in 1912.^[4] He also published a paper on regularization methods in mechanics in 1912.

Awards, recognition

Sundman was awarded the Pontécoulant prize by the French Academy of Science in 1913 for his work on the 3-body problem.^[1] In 1908 Sundman was elected member of the Finnish Society of Sciences and Letters^[5] and in 1947 foreign member of the Royal Swedish Academy of Sciences.^[6] The crater Sundman on the Moon is named after him, as is the asteroid 1424 Sundmania.
