摘要: 用Faedo-Galerkin方法研究有界区域上具有非线性阻尼项和时滞项的三维磁流体方程, 解决了解的适定性问题. 首先, 证明当α≥16/5时强解的存在性; 其次, 利用Gagliardo-Niernberg不等式证明强解的唯一性.

Abstract: We used the Faedo-Galerkin method to investigate the three-dimensional magnetofluid equations with nonlinear damping terms and  delay terms on a bounded domain  and solved the problem of well-posedness of the solutions. Firstly, the existence of strong solutions was proven when α≥16/5. Secondly, the uniqueness of strong solutions was proven by using the Gagliardo-Niernberg inequality.

Key words: three-dimensional magnetofluid equation, damping, delay, well-posedness
