A 3D ray plot shows how hard this Jacobian counterexample is to read
moultano · x · 2026-07-22
- The post points to a Jacobian counterexample and asks whether there is a natural way to visualize it.
- The attached figure shows a dense 3D ray plot from 3D inputs to 3D outputs, making the mapping look highly tangled and hard to interpret.
- The underlying point is about whether such counterexamples can be made more intelligible through visualization, rather than just stated algebraically.
