Stable singularity found on 3D Euler using PINNs, Anandkumar team reports
anshulkundaje · x · 2026-09-09
Anima Anandkumar's team reports a stable singularity on 3D Euler. The approach uses a physics-informed neural network (PINN) to find an approximate profile, then argues stability around it to complete the proof. PINNs typically converge to trivial solutions on such problems; the team nudges them toward interesting regions via a novel combination of constraints, plus a detailed study of the transport field.
