Abstract
In this paper, we prove that suitable weak solution (u, b) of the 3-D MHD equations can be extended beyond T if u ∈ L ∞(0, T;L 3(ℝ3)) and the horizontal components b h of the magnetic field satisfies the well-known Ladyzhenskaya–Prodi–Serrin condition, which improves the corresponding regularity criterion by Mahalov–Nicolaenko–Shilkin.
