Adjoint Transfer and Order-Lifting Dichotomies for 2 x 2 Matrices over Prime-Power Rings

We study determinant-compatible lifts of invertible 2×2 matrices over odd prime-power rings through an affine first-variation formula for matrix order defects and cyclic adjoint transfer on the traceless tangent space. We classify the full-order transfer for scalar, semisimple, a...
