2025-04-09 π4/90 = 1.082323233… ﾊﾞｰｾﾞﾙ問題の次の一歩前回､ﾊﾞｰｾﾞﾙ問題 1 + 1/22 + 1/32 + 1/42 + 1/52 + ··· = π2/6 のｴﾚｶﾞﾝﾄな別証明を紹介した｡同じ証明法の自然な応用として､4乗数の逆数の和1 + 1/24 + 1/34 + 1/44 + 1/54 + ··· = π4/90 を考えてみたい｡π2 は 9.87 に近い――｢987ﾉﾃｯﾍﾟﾝｶﾗﾄﾋﾞｳﾂﾚ｣（ﾓﾄﾈﾀは漫画｢わたしは真悟｣）ってのは､この値を指す｡そのまた平方に当たる π4 は､大ざっぱに 102 = 100｡もうちょい精度､上げると:9872 = (1000 － 13)2 = 100万 － 2万6000 + 132 = 97万4000 + 132132 = 169 なので 97万4169 だが､ここでは下3桁を無視｡ 100 のｵｰﾀﾞ

2024/6/7 Geometric Modeling and Processing 2024, Qingdao久しぶりにちゃんと学会で講演を聞いた気がするのでﾒﾓを取っておこうと思います｡ｱﾙｺﾞﾘｽﾞﾑの話が難しい…｡Denis Zorin: Metric Optimization in Penner Coordinates. ｸｱｯﾄﾞﾒｯｼｭを作成するために､局所的ｻｰﾌｪｽﾊﾟｯﾁを平面に展開するﾌﾟﾛｾｽがある｡その際､辺の長さが負にならないという制約付きの最適化計算が必要だが､制約付きは解きにくい｡本研究では､負の長さの辺を許して最適化しておいて､あとから辺のｽﾜｯﾌﾟで正しい平面ﾒｯｼｭにする手法を開発した｡Kai Hormann: Compressing geodesic information for fast point-to-point geodesic distan
