What's the most natural way to establish the asymptotics of \Delta $\Delta$ on a compact Riemannian manifold M of dimension N? The asymptotics should be
#(values $$\#\{v < A^2) A^2\} = const*vol(M)*A^n \mathrm{const}*\mathrm{vol}(M)*A^n + O(something)
o(\mathrm{something})$$
(Perhaps one could consider first a case of Kahler manifold? The Laplacian is partiularly simple there).
