題目:Global Regularity of the 2D Incompressible Generalized Magneto-micropolar Equations

內(nèi)容簡(jiǎn)介:In this talk I will present the global regularities of the generalized 2D magneto-micropolar equations with partial magnetic diffusion and fractional dissipation. For the first case the velocity field is ideal, the micro-rotational velocity is with Laplacian dissipation and the magnetic field has fractional partial diffusion $(-\partial^{\beta}_{22}b_1, -\partial^{\beta}_{11}b_2)$ with $\beta>1$. In the second case, the velocity has a fractional Laplacian dissipation $(-\Delta)^{\alpha}u$ with any $\alpha>0$, the micro-rotational velocity is with Laplacian dissipation and the magnetic field has partial diffusion $(-\partial_{22}b_1,-\partial_{11}b_2)$. I also present the results for a Cauchy problem of the 2D Leray-$\alpha$ regularized incompressible magneto-micropolar equations. The global smooth solution of the Cauchy problem for the equations with zero angular viscosity and zero magnetic diffusion or with only angular viscosity and magnetic diffusion are established.
