Eigenvalues of laplacian operator
WebMay 2, 2012 · If $\lambda_v, \lambda_w$ are the corresponding eigenvalues, then the eigenvalue associated to $v \otimes w$ is $\lambda_v + \lambda_w$. Observe now that the $d$-dimensional grid is just the Cartesian product of $d$ copies of the $1$-dimensional grid, so it suffices to answer the question for $d = 1$.
