Theorem · version 1

Blowup with external forcing

Statement

There are finite-energy solutions of the forced incompressible Euler equations on ℝ³, with velocity in C^{3,1/2} before blowup and a force uniformly bounded in C^{1,1/2−ε} ∩ L², that form a singularity in finite time.

Assumptions

  • Three-dimensional incompressible Euler equations.
  • Reported in the 2026 manuscript’s historical context.

Scope

A force is applied; the question asks about unforced evolution.

    Elgindi (Annals 2021) proved finite-time blowup on ℝ³ for C^{1,α} axisymmetric velocities without swirl, for small α > 0. Córdoba and Martínez-Zoroa (2023) constructed finite-energy forced Euler solutions on ℝ³ that blow up. For smooth initial data, Chen and Hou (2022; rigorous numerics 2025) proved blowup in an axially periodic cylinder with an impermeable wall.
