AbstractThe velocity $ \vec v $ of an incompressible flow in a bounded three‐dimensional domain is represented by its vorticity $ \vec j $ with the help of an apparently new representation formula. Using this formula we prove a quasi‐Lipschitz estimate for $ \vec v $ in dependence of the supremum norm of $ \vec j $. Our quasi‐Lipschitz bound extends to the case where $ \vec v $ is represented by any continuous $ \vec j $ ≠ rot $ \vec v $
