Abstract

This paper develops a mirror symmetry theory of Spencer cohomology within the geometric framework of constrained systems on principal bundles, revealing deep symmetric structures in constraint geometry. Based on compatible pairs $(D,\lambda)$ under strong transversality conditions, we construct a systematic family of mirror transformations: from basic sign mirrors $\lambda \mapsto -\lambda$ to general automorphism-induced mirrors $\lambda \mapsto (d\phi)^*(\lambda)$. Our core result proves that these transformations preserve all geometric properties of compatible pairs and induce natural isomorphisms between Spencer cohomology groups. This theory unifies constraint mechanics, gauge field theory, and differential topology, establishing a complete mathematical framework for symmetry analysis of constraint systems and revealing the special mirror structure of Spencer complexes in constraint geometry.
