Abstract
In this paper, we investigate the blowup phenomenon of solutions for two-dimensional transverse magnetohydrodynamic (MHD) equations. By using the integration method, we first prove that the classical solutions for of the transverse MHD equations with the initial bounded region surrounded by vacuum will blow up in finite time. Furthermore, we also establish the finite-time singularity formation of the classical solutions for to the transverse MHD equations with a class of non-vacuum initial values.
