… Nowadays, the function that is determined when a measure μ of a general space X and a function K ( x , y ) of X × X are given is called a potential with K as the kernel and μ as the mass distribution, and the theory related to such functions is called potential theory. When X is a three-dimensional Euclidean space, the Newton potential has K ( x , y ) = | x - y | -1 as the kernel (the same as above with d μ = - G ρ dV ). In two-dimensional Euclidean space, the logarithmic potential with K ( x , y ) = -log | x - y | as the kernel is important. … *Some of the terminology that mentions "Newton potential" is listed below.

… 現在では,一般の空間Xの測度μとX×Xの関数K(x,y)が与えられたときに決まる関数,のことを〈Kを核としμを質量分布とするポテンシャル〉と呼び,このような関数に関連した理論をポテンシャル論という。Xが三次元ユークリッド空間のとき,K(x,y)=|x-y|-1を核とするものをニュートンポテンシャルNewton potentialという(dμ=-GρdVとしたものがちょうど前述のものである)。二次元ユークリッド空間では,K(x,y)=-log|x-y|を核とする対数ポテンシャルが重要である。… ※「Newton potential」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 |
