Eigenvalues of laplacian operator
WebMar 19, 2016 · This is how Fourier series come up. This works because sine and cosine with the correct arguments are eigenfunctions of the Laplacian, which is a self-adjoint operator and the eigenfunctions of a self-adjoint operator form a basis for the solution space. – User8128. Mar 19, 2016 at 16:00. WebThe Laplace operator on functions in Euclidean space is fundamental because of its translational and rotational invariance which makes it appear in problems like the heat …
