Fable 5 just solved this problem that Jacobian Conjecture Claude's Fable 5 Just Solved a Maths Problem That Was Basically Impossible to Solve for 87 Years for 87 years it's called the Jacobian conjecture imagine an infinite 3d complex space every point anywhere new but you can only use addition subtraction or multiplication in other words you can use polynomial equations to build this entire system called a polynomial map at any single point you can zoom in and check something called the Jacobian determinant think of it as a local stretch factor that tells you whether the space around a point gets stretched squeezed or crushed flat so nearby points become impossible to tell apart now suppose that number comes out to be some constant non zero value at every single point in the entire space no matter where you zoom in nothing ever gets flattened the question is does that guarantee the whole transformation is globally reversible that every final point came from exactly one starting point or could two completely different starting points in the exact same place even though everything looks perfectly fine that's the core of the Jacobian conjecture for 87 conjecture for 87 years mathematicians believed the answer was yes but nobody could prove or disprove it then came fable the jacobian conjecture 1939-2026 det J = -2 everywhere and told to reason from first principles nobody was expecting a polynomial map determinant of minus two where one point could be traced different starting points Fable 5 one that was enough to falsify an 87 year old mathematical belief first posted by the result still needs peer review holds up just settled one of the biggest problems in mathematics you can talk it and watch it lose its mind
