Abstract:We investigate constrained quantum motion on curves and surfaces using connection factorization methods. We show that Laplace operators admit an exact half-connection factorization generated by connection one-forms. The first-order part of the Laplacian is identified with the Darboux rotational connection of the orthogonal frame. Elimination of this rotational connection naturally produces quadratic geometric invariants analogous to supersymmetric Riccati potentials. Using orthonormal moving frames, we derive effective geometric contributions for planar curves, spatial curves, and embedded surfaces. We further analyze Dirac reductions using structure equations and show that for Fermi-type reductions the scalar Jensen--Koppe--da Costa contribution is cancelled in the reduced Dirac sector, leaving a residual first-order spinorial derivative structure. The resulting framework suggests the existence of hidden nilpotent covariant differential complexes naturally generated by geometric connection structures.
