Regulated Spectral Accumulation in Elliptic Partial Differential Operators

Divergence in spectral partial differential equations is traditionally addressed through truncation, renormalization, or asymptotic subtraction. ^[3][4] These techniques repair symptoms rather than structure. This paper applies the Additive–Multiplicative (AM) Regulator as a fixed mathematical framework to spectral PDEs, showing that divergence arises solely from unregulated accumulation of eigenmodes. ^[6][7] Without modifying operators, equations, or boundary conditions, regulated spectral accumulation produces finite heat traces, controlled Green’s functions, and compactness at fixed constraint. Classical results are recovered exactly as degeneracy limits. The conclusion is blunt: divergence in spectral PDEs is not intrinsic; it is a consequence of unconstrained aggregation.
