Abstract

Abstract We present a novel geometric and spectral approach to compare the energy efficiency of 3D foam structures, focusing on the classic Kelvin foam and the Weaire-Phelan (WP) structure. Using differential geometric analysis and spectral graph theory, we construct a symbolic energy model based on mean curvature and Laplacian eigenvalues. We prove two new theorems linking curvature flow energy to spectral gap rigidity, and validate our claims with analytical bounds and numerical visualization. This hybrid method provides a symbolic foundation for foam optimization, extending prior numerical-only approaches.
