This is the construction / computation page for my joint paper with Zsuzsanna Dancso, Ribbon 2-Knots, $1+1=2$, and Duflo's Theorem for arbitrary Lie algebras (PDF here).
Abstract. By performing the calculation "$1+1=2$" on a 4D abacus, we explain in the most direct way we know how the study of "expansions", or "universal finite type invariants", for ribbon 2-knots leads to a proof of Duflo's theorem for arbitrary finite-dimensional Lie algebras. This complements the results of B-N, Le, and Thurston [BLT] where a similar argument using a 3D abacus and the Kontsevich integral was used to deduce Duflo's theorem yet only for metrized Lie algebras, and our results from [BND2] which also imply a relation of 2-knots with the full Duflo theorem, though via a lengthier path.
