椭圆算子 meaning in English
elliptic operator
Examples
- Characteristic sets of the grushin operator
亚椭圆算子的特征集 - Part 2 we consider the following second - order hyperbolic equation with a a uniformly elliptical operator independent of t
第二部分：我们考虑以下二阶双曲型问题算子a一致椭圆算子且与t无关。 - The theory of dealing with elliptic operator is given and proved , which divides the inner product of the operator into two operators that are estimated one by one
摘要给出了一类线性椭圆算子的处理方式中有关结论的证明，该结论巧妙地将椭圆算子作内积后分为两部分进行处理，进而得到它们的估计。 - In chapter 6 , we study existence of the weak solutions for a class of the nonlinear dirichlet problems on h " and estimates of the eigenvalues about the subelliptic operators on heisenberg group
最后，我们在heisenberg群上研究几类半线性次椭圆方程的弱解存在性问题和几类次椭圆算子的特征估计问题。
