Karl F. Sundman

Karl Frithiof Sundman (28 October 1873, Kaskinen – 28 September 1949, Helsinki)[1] was a Finnish mathematician who used analytic methods to prove the existence of a convergent infinite series solution to the three-body problem in 1906 and 1909.[2][3] He also published a paper on regularization methods in mechanics in 1912. In the 1990s, Qiudong Wang generalized Sundman's solution to the case of more than three bodies.[4][5][6]

Awards, recognition

Sundman was awarded the Pontécoulant prize by the French Academy of Science in 1913 for this work.[1] In 1947, Sundman was elected a foreign member of the Royal Swedish Academy of Sciences. The crater Sundman on the Moon is named after him, as is the asteroid 1424 Sundmania.
