Abstract

We study the blow-up criterion of smooth solutions to the 3D MHD equations. By means of the Littlewood-Paley decomposition, we prove a Beale-Kato-Majda type blow-up criterion of smooth solutions via the vorticity of velocity only, i. e. j∈∫0T\|Δj(× u)\|∞ dt, where Δj is a frequency localization on |ξ|≈ 2j.
