数学年刊第１８卷Ｂ辑第２期（１９９７）目次和提要椭圆型方程内边界问题应隆安给了一个新的方法研究二阶椭圆方程内边界问题奇点附近解的正则性．对于一般的主部非对称的、具有间断的分片光滑系数的方程，证明了Ｈ１的解可以分解成两部分，一部分是对应的分片常数系数的... Annals of Mathematics, Volume 18, Issue B, No. 2 (1997) 目次 及 提要 The Boundary Problem of Elliptic Equations Should be a new method to study the regularity of the solution of the singularities within the boundary problem of second-order elliptic equations. For the general main part of the asymmetric, with intermittent smoothing coefficient of the equation, proved that the H1 solution can be decomposed into two parts, part of the corresponding piecewise constant coefficient ...
