,〔(久留島喜内 ) -- Chiba University, (Dept. of Mathematics and Infomatics )〕 also known as Kurushima Yoshita〔( List of Japanese mathematicians ) -- Clark University, ( Dept. of Mathematics and Computer Science )〕 and ,〔( WorldCat Identities ): ( 久留島義太 -1757 )〕 was a Japanese mathematician in the Edo period.〔Smith, David. (1914). 〕 The Japanese board game of shogi attracted Kurushima's interest; and he was recognized in his own time as a master player.〔Shogi, ("Famous Mate Problems" -- #62, #63, #68, #69, #79 )〕 Among shogi players, he continues today to be well known for seven "puzzle ring" gambits with subsequent sequenced maneuvers—including the "silver puzzle ring."〔''La Revue de l'Association Française de Shogi,'' Juillet 1998, Numéro 19, p. 4.〕 In his lifetime, he was recognized among the most prominent intellectuals. His mathematical gift was highly esteemed.〔Smith, 〕 Kurushima, like most of his contemporaries, was very interested in the mathematical problems involved in "magic squares."〔Michiwaka, Yoshimasa. (1997). "Magic Squares in Japanese Mathematics," 〕 ==Selected works== Kurushima's published writings are few.〔 * ( OCLC 033747221 ) * (OCLC 033745707 ) * (OCLC 033746085 ) * (OCLC 033745451 ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kurushima Kinai」の詳細全文を読む スポンサード リンク
