摘要
考察在两维平面上,当边界并非光滑的情况下,一类一阶椭圆型方程组的边值问题.采取了Schauder估计的方法,选取一种加权的Hlder范数,通过将一阶椭圆组化为二阶的形式,利用二阶椭圆方程相关结果,得到了方程组的正则性和Fredholm型可解性结果.
A boundary problem for first order elliptic system of differential equations in two dimensional domain with nonsmooth boundary is considered. The problem is changed to a corresponding boundary value problem for an elliptic equation of seoond order. By using the estimates in a weighted Holder space for second order equations, a priori estimates for the first order elliptic system is established. Then the regularity theorem and Fredholm alternative existence theorem for our boundary value problem are proved.
