Mathematicians Coax Fluid Equations Into Nonphysical Solutions | Quanta Magazine
The famed Navier-Stokes equations can lead to cases where more than one result is possible, but only in an extremely narrow set of situations.
Hasnain says:
“The new paper does not definitively settle whether Leray solutions are unique. Its conclusions rely on an external force crafted specifically to make non-uniqueness occur. Mathematicians would prefer to avoid the addition of a force altogether and prove that some set of initial conditions leads to non-uniqueness without any outside influence. That question is now perhaps a stone’s throw closer to being answered.”
