A boundary value problem is a problem of finding a solution to a differential equation that satisfies a differential equation in a certain region and satisfies the conditions given on the boundary of this region. In this case, the conditions given on the boundary are called boundary conditions. Second-order ordinary differential equation (p(x)y')'+(q(x)+λ)y=0 Boundary value problems can also be considered for partial differential equations. For example, when D is a bounded domain in three-dimensional space and its boundary S is sufficiently smooth, the equation [Yoshikazu Kobayashi] [Reference item] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
微分方程式に関し、ある領域で微分方程式を満たし、この領域の境界で与えられた条件を満たす解を求める問題を境界値問題という。このとき境界上で与えられた条件を境界条件という。二階常微分方程式 偏微分方程式についても境界値問題が考えられる。固有値問題としては、たとえばDを三次元空間の有界領域でその境界Sが十分滑らかであるとき、Dで方程式 [小林良和] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
