本文将Dirichlet和Neumann边界条件下等边三角形上Laplacian的本征值和本征函数的Lamé公式推广到具有吸收边界条件的Robin问题。它们被示出形成一个完整的正交系统。各种属性的频谱和模态函数进行了探讨。AMS科目分类:35C05、35J05、35P10
Lamé’s formulas for the eigenvalues and eigenfunctions of the Laplacian on an equilateral triangle under Dirichlet and Neumann boundary conditions are herein extended to the Robin problem with an absorbing boundary condition. They are shown to form a complete orthogonal system. Various properties of the spectrum and modal functions are explored. AMS Subject Classification: 35C05, 35J05, 35P10
