## Existence of weak solutions to the three-dimensional density-dependent generalized incompressible magnetohydrodynamic flows

 1 School of Mathematical Sciences, Xiamen University, Xiamen 361005, China

Received  August 2013 Revised  August 2014 Published  October 2014

In this paper we consider the equations of the unsteady viscous, incompressible, and heat conducting magnetohydrodynamic flows in a bounded three-dimensional domain with Lipschitz boundary. By an approximation scheme and a weak convergence method, the existence of a weak solution to the three-dimensional density dependent generalized incompressible magnetohydrodynamic equations with large data is obtained.
