摘要：
This paper considers the problem of the local existence for the generalized MHD equations with fractional dissipative terms Lambda 2 alpha u for the velocity field and Lambda 2 beta b for the magnetic field, respectively. Based on some new commutator estimates, local existence for the generalized MHD equations is established, which recovers and improves previous results.
