Indeed, any previous reasoning contained at some point numerical simulations, which are not a proof in mathematical sense, as the wording "the conjecture is true" implies. Moreover, no reasoning about n = 3 is provided in Andreatta et al., but only a quite heuristic proof for n = 2. The case n = 1 is trivial. All cases n <= 3 are anyway treated rigorously in Lombardi, 2022 undo Tags: Manual revert Reverted Mobile edit Mobile web edit

• curprev 05:2505:25, 22 June 2022 David Eppstein talk contribs 44,357 bytes +18 Undo continued promotionalism, apparently by someone trying to hype up their own research. Z&L 1994 claim to have a proof of a solution. Andreatti et al accept it as a proof. It uses some computer-based calculations but that does not make it less of a proof. Another proof that avoids the calculations is a good thing, but not something to be trumpeting from the rooftops. undo Tags: Undo Reverted

The work of Zalgaller, providing the analytical argument missing in Gabai and Liban, was inserted. The work of Zalgaller and Los' was better described as including numerical arguments in providing the result. The latest paper providing the analytical proof of their result about the Malfatti's problem and completing this solution was cited and shortly described. undo Tag: Visual edit
