We assume that B-matrix chains which are a product of the numerical statistical theory called Cairo technique are capable of efficiently solving the SE PDE in 1D, 2D, 3D via two natural laws or principles:
* 1-simultaneity and 2- the Pythagorean theorem,
without going through SE itself.
We also assume that our fellow Researchgate contributors can provide an equivalent or even better answer independently.
Your suggestions are greatly appreciated.
