Regularity and decay of 3D incompressible MHD equations with nonlinear damping terms. (English) Zbl 1316.35247
Summary: We prove the existence and uniqueness of global strong solutions to the Cauchy problem for 3D incompressible MHD equations with nonlinear damping terms. Moreover, the preliminary $$L^{2}$$ decay for weak solutions is also established.
