  "summary": "Unresolved in this packet after the dated source check. Strongest checked result: The complex conjecture in every dimension reduces to cubic homogeneous maps. Dimension one is elementary, and several restricted plane cases are proved. Exact unresolved remainder: For every polynomial F:C^2 to C^2 with constant nonzero Jacobian determinant, prove that F has a polynomial inverse. Higher-dimensional complex cases remain open as well.",
