T₃拓扑弹性场论: 超欧拉旋量代数及其在刚体旋转与多维形变中的应用 T₃ Topological Elastic Field Theory: Hyper‑Euler Spinor Algebra and Its Applications in Rigid‑Body Rotation and Multidimensional Deformation

Since Hamilton proposed quaternions, with the 4π spinor periodicity and freedom from gimbal lock, quaternions have become the dominant mathematical tool for rigid‑body rotation and three‑dimensional attitude control. Nevertheless, conventional quaternions are purely algebraic constructs. They can only describe attitude transformation, and fail to capture internal scale deformation, topological shear, as well as path memory generated during successive multi‑fold rotations. Based on T₃ topological elastic field theory, this report introduces the novel T₃ hyper‑Euler spinor. Derivation proves that under the pure elliptical phase reduction condition, the T₃ spinor exactly reproduces the 4π periodic property of quaternions. In the general physical regime, the T₃ spinor upgrades classical rigid rotation into an integrated dynamical engine with three channels: scale evolution (α channel), hyperbolic deformation (β channel) and elliptical spin (γ channel). This paper systematically elaborates the mathematical structure of T₃ spinors, the non‑associative topological memory effect, and lists promising applications in aerospace, physics engines, intelligent materials and quantum computation.
