… In the second half of this century, with the development of computers, numerical solutions to the three-body problem began to be researched. Because the celestial bodies were regarded as point masses, reliable numerical solutions could not be obtained when two celestial bodies approached each other, but in 1967, V. Szevehely and C.F. Peters, then at Yale University, showed that this difficulty could be eliminated by applying a regularization called the Kusternheimo-Stiefel transformation to the equations of motion. In other words, the three-body problem could be solved numerically (the four-body problem has not been solved numerically). … *Some of the terminology that mentions "Szevehely, V." is listed below.

… 今世紀後半になってコンピューターの発達とともに三体問題の数値的解法が研究されるようになった。天体を質点とみなすため,2天体の接近によって信頼できる数値解が得られなかったが,1967年に運動方程式にクスターンハイモ=スチーフェルの変換という正則化をほどこしてその困難が除かれることが,当時イェール大学のサブヘイV.Szevehely,ピータースC.F.Petersによって明らかにされた。つまり三体問題は数値的に解けたということになる(四体問題は数値的に解けていない)。… ※「Szevehely,V.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
