椭圆型方程关于时间参数正则性估计

有关解在时间t方向上的正则性是在解决发展方程组耦合问题过程中一直关注的目标。由于在解决一些如椭圆－抛物型方程组耦合问题、椭圆－双曲型方程组耦合问题等，都会碰到椭圆型方程中关于时间t正则性的估计，为此这里针对椭圆型方程关于时间参数t的正则性进行分类讨论，旨在让同行的工作者更方便地应用有关这些正则性的结果。

REGULARITY OF ELLIPTIC EQUATION IN TIME DIRECTION

The main purpose is to deal with the regularity of the solution for elliptic equation in time direction. The regularity of evolutionary equations in time direction is always one of the most important aims being payed close attention to. When to solve problems such as those with elliptic-parabolic equations and for elliptic-hyperbolic systems and so on, such situations will be met as to how we estimate the regularity of the solution for elliptic equation in time direction. For this reason it is hoped that the results can do some help for a deeper understanding of these problems.
