| contents | We establish a criterion for the validity of the classical (non-semiclassical) Weyl law for Schrödinger operators $ H=Δ+V $ on complete Riemannian manifolds. In contrast to existing results, our approach does not rely on standard geometric assumptions such as bounded geometry, nor on analytic assumptions such as the doubling condition on the potential. Instead, we identify a geometric-analytic invariant that encodes the precise balance between the geometry of the manifold, the growth of $V$, and the oscillation scale of $V$. This intrinsic quantity, denoted $c_δ(λ)$ admits effective quantitative estimates. We prove that the Weyl asymptotic holds provided $\lim_{λ\to\infty} c_δ(λ)=0 .$ The sharpness of this criterion is demonstrated through explicit examples showing that the Weyl law can fail when the criterion is violated. |
