His results gained fame when they were reproduced in Acta Mathematica in 1912. 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 Sciences in 1913 for his work on the 3-body problem. and in 1947 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.
