我们证明了闭流形M的拉普拉斯算子的特征值在某种意义上可以用M中的I-网的图的拉普拉斯算子的特征值逼近为n -*oo。我们的近似除了维数外不需要对M作任何假设。
We show that the eigenvalues of the Laplacian of a closed manifold M is approximated in a certain sense by the eigenvalues of the Laplacian of the graph of a I-net in M as n -*oo . Our approximation needs no assumption on M except for dimension.
